CN Bridge expansion: when transit intersects

Did you know that as part of vivaNext’s rapidway project on Highway 7 West in the City of Vaughan, construction is underway to expand the south side of the Canadian National Railway [CN] MacMillan Bridge? The bridge surface, located west of Keele Street will be widened approximately 8-metres to accommodate dedicated rapidway lanes, sidewalks and bicycle lanes.

Aside from being one of the most widely-used bridges along Highway 7, most drivers may not even realize that each time they cross the bridge, they are driving over the CN MacMillan Rail Yard, the largest rail yard in Canada.

Named after former CN president, Norman John MacMillan, the yard measures approximately 6.5-kilometres in length and 1.6-kilometres in width and was developed in the late 1950s as part of CN’s redesign of the Toronto trackage network. The yard operates 24 hours a day, 7 days a week and handles over 1 million railcars per year to service local businesses in the Vaughan area, as well as the broader North American economy!

As part of the bridge widening, construction activities include:

  • removing the existing walls and sidewalks on the south side
  • backfilling with 8,000 tonnes of earth
  • pouring 4,000 tonnes of concrete to build walls, columns, sidewalks and bridge decks
  • embedding 300 tonnes of reinforcing steel and;
  • completing the surface finish with new light standards and pedestrian hand rails.

Sounds like a lot right? So how do we do this without impacting CN’s business?

During construction, rail yard operations along the 10 sets of tracks will be maintained, and the contractor will work closely with CN to coordinate activities around train schedules. The majority of the construction activity will happen below and underneath the bridge. Motorists will notice large equipment and construction vehicles such as large cranes, transport trucks, drill rigs and concrete pump trucks onsite for certain operations, including sub-surface drilling, pouring concrete and the installation of large pre-cast concrete sections.  With the increase in construction vehicles, safety awareness is important if you are travelling through the area.

In order to maintain traffic flow along Highway 7 during the bridge expansion, the centre median was removed earlier this year and traffic was shifted to the north side of the bridge. To further minimize disruptions, an access road off of Highway 7 is also being constructed for equipment and deliveries. Due to the nature of this work, there will be noise and vibration around the work area. Being mindful of our neighbours, noise and vibration monitoring will be conducted to ensure levels are kept within industry standards.

The first phase of the Highway 7 West rapidway in the City of Vaughan will extend 3.6 kilometres from Interchange Way/Edgeley Boulevard to east of Bowes Road. The project features three new rapidway vivastations, wider sidewalks, landscaped boulevards and transit connections to the Toronto-York Spadina Subway Extension and the York Region Transit Bus Terminal. The CN Bridge expansion work in Vaughan is expected to be complete in 2016.

transforming vaughan

VivaNext is committed to designing and delivering an exceptional rapid transit system – one that will help shape growth in our communities, connect York Region’s urban centres and provide faster, more reliable and congestion-free trips. The vivaNext rapidway in Vaughan is more than just a transit project. It also includes urban design elements such as pedestrian-friendly boulevards, wider sidewalks, attractive landscaping, bicycle lanes and green open spaces for the whole community to enjoy. Check out this video and take a ride with us along the corridor to see what is happening.

As you can see, the transformation along Highway 7 West is well underway. Last year, in the Vaughan Metropolitan Centre [VMC] area (also known as phase one of the vivaNext project in Vaughan) crews were busy removing signs, and relocating utilities in preparation for construction.

This year, you will see significant construction activity in this segment. Traffic lanes will be shifted and bus stops will be relocated in order for crews to continue infrastructure work for hydro, gas, storm drains, watermains and begin road widening. Construction has also started on the south side of the Canadian National Railway [CN] Bridge, located west of Keele Street. The bridge surface will be widened approximately 8-metres to accommodate dedicated rapidway lanes, sidewalks and bicycle lanes.

In the phase 2 area east and west of VMC, crews will be working intermittently along the corridor on preliminary construction activities such as soil sampling and other environmental investigations.

Work on the Toronto-York Spadina Subway Extension [TYSSE] also continues this year.  When completed, this subway line will include six stops, 8.6 kilometres of track. Residents and visitors alike will enjoy the mixed-use, transit-oriented development offered in the VMC area, including convenient passenger pick-up and drop-off, a York Region Transit bus terminal, and connection to the Viva rapidway running in dedicated lanes east and west along Highway 7. It will be a great place to work, shop or relax, and getting there will be easy whether you walk or ride transit.

Throughout construction, we’ll keep everyone informed and minimize disruptions as much as possible for those who live, work and commute in Vaughan. For more information on any of these projects, or to sign up for construction notices so you can stay in the loop, visit vivanext.com.

spring has arrived on davis drive

I’m sure I’m not the only one who’s very excited to see the long harsh winter [or “polar vortex” as the media described it] come to an end. The bone-chilling temperatures were all too frequent this winter and I’ve almost forgot what weather in the positive double digits feel like, but we are excited to see the sunshine!

While it may not feel like spring has completely sprung yet, the extra daylight and warmer temperatures are a welcoming addition to each day.  We are embracing this nicer weather at vivaNext and are gearing up for a very busy construction season on Davis Drive.

This year the transformation will continue to take shape with significant work set to get underway. Road widening and base layer paving will be a major focus this year. You’ll also see finished boulevards in sections. Planters with interlocking paving stones and concrete sidewalks will be installed in these areas.

For larger operations, some work is required deep underground. This year multiple closures on side streets that intersect Davis will be required for several different operations. The most up-to-date details on all the road closures off Davis Drive are available at vivanext.com.

It’s also necessary at times to close or relocate bus stops and shelters so construction crews can gain access to work sites and to ensure the public is kept safe during construction. To find out if a bus stop has been moved to a temporary location please watch for signs that will direct you to the closest open bus stop. There’s a lot going on out there so we’ve made a short video to assist you with what to look for when a bus stop has been relocated.

Updates about all of this work will be made available as they happen. If you have questions or concerns please contact your Community Liaison and sign up for construction updates to get the latest construction information at vivanext.com.

spring is in the air

John Steinbeck – “What good is the warmth of summer, without the cold of winter to give it sweetness.” Such words have never been truer than this past winter.  The Greater Toronto Area recorded the coldest winter in 20 years; there have been at least 10 days of temperature that dipped below -20 C, which hasn’t happened in seven years and this has been the longest winter on record in over 100 years! With the official arrival of spring, vivaNext is preparing to ramp up our construction and road work.

Last year, we had some great milestones with the opening of 3.9 kilometres of rapidway on Highway 7 from Bayview Avenue to Highway 404. The Toronto-York Spadina Subway Extension [TYSSE] project celebrated a major milestone at the end of last year, with the tunnel boring machines [TBMs] “Yorkie” and “Torkie” finished their tunneling journey north to Vaughan Metropolitan Centre [VMC] station. Ongoing utility relocation on Highway 7 West, as well as CN Bridge work.  On Davis Drive, nearly all retaining walls have been constructed, the eastern creek culvert has been replaced and extended, and the majority of hydro poles have been relocated. Road widening and base-layer paving has started, while reconstruction of Keith Bridge and the extension of the western creek bridge on the north side continue.

Building on the progress and advancing the BRT project, we’ll continue to relocate utilities, construct retaining walls, widen roads and pave along the different corridors, not to mention finishing the new viva stations on Highway 7 in Markham.  With the longer days and bright sunshine, comes a lot more activity in the construction zones so please drive carefully and be alert to workers in the area. We know construction can be daunting and we thank you for your patience and understanding. Please drive with care and give yourself extra time to get to your destination safely.

To find out what is happening this spring, follow us on Twitter and like us on Facebook. You can also sign up for email notices at vivanext.com to keep you updated on the construction underway in your area.

taking care near our urban watercourses

If you’ve been at the corner of Jane Street and Highway 7 in Vaughan recently, you’ll have seen the work underway to build a 10 metre long retaining wall near where the Black Creek flows through a large culvert under the roadway.

We’re building the retaining wall to support the newly widened roadway. Ensuring that our project does not negatively affect any of the watercourses adjacent to or crossing our rapidway segments is a top priority for vivaNext, and we have made commitments through the Environmental Assessment phase of the project for how we will carry out that work to ensure there are no harmful effects.  In keeping with this commitment, we need to have the major work on the retaining wall finished this spring before April 1, completing the in-water work before the closing of the pre-established work window.

This “work window” is set by the provincial Ministry of Natural Resources, and is set out in timing guidelines that are applied to construction projects near or in watercourses that are home to any species of fish.  These timing guidelines are intended to protect fish from any impact from construction work being done in or around water, during the critical life stages for fish including spawning migrations, egg incubation and fry emergence.

Provincial guidelines are organized by region as well as by fish species within those regions.  Fish can be divided into those that spawn in cold water (i.e. in the spring) and those that spawn in warm water (i.e. in the fall), with the species in the Black Creek being in the cold-water group.  For that reason, the construction permits require that any work we do in or near the Black Creek be done outside of the period from April 1 to June 30, to ensure that the project doesn’t interfere with their spawning.

Once the work window closes April 1, we will not do any work in or around the water until the beginning of July.  So we go to great lengths to ensure the work on the Black Creek retaining wall is finished by the end of March, and that we won’t need to do any other activities involving in-water work until the summer.

Our commitment to ensuring our work has no adverse effects on the environment goes well beyond avoiding any in-water work at sensitive times.  On all our segments, we work closely with the local conservation authorities, who approve the final designs before we get their permission to work.  Our mutual goal is to ensure the project, at a minimum, avoids any harmful impacts, and in many cases actively enhances the natural environment. We also use various construction strategies to mitigate any potential impacts while we’re working, such as installing cofferdams from sheet piles or sand bags around our work zones within watercourses.   By using these methods, we’re able to work “in-the-dry”, thereby avoiding any risks to the watercourse and its fish, even if the in-water work window has closed.

We’re happy to know that the vivaNext project is going to ultimately enhance our shared environment for people and the other creatures that live in York.  So taking great care as we work near our creeks and rivers is just one example of how we’re committed to protecting and enhancing our natural surroundings, even in a fully-urbanized area like Highway 7 and Jane Street.

Please remember as the temperature heats up during spring thaw, water ways and creeks can been extremely dangerous, remember to keep a safe distance.

winter work to make our spring schedule

With its cold temperatures, snow and ice, winter is not the ideal construction season for roadwork in general, which is why most vivaNext construction is focused on other tasks for the next few months.  But to make sure we’re ready to get going on roadwork as soon as it’s warm enough next Spring, our crews and those of various utility companies are keeping busy this winter doing a range of activities.  Here’s what you can expect to see going on out there this winter.

A key task for all the vivaNext corridors is widening the roads so we can keep the existing number of travel lanes, plus make room for the rapidways and stations in the median.  But before we can get going on construction to make the roadways wider, we need to remove and relocate all the utilities that previously ran beside the curb of the existing roadways.  This step, which involves relocating a wide range of services including gas, hydro, telecommunications, water, and sanitary and storm sewer systems, requires painstaking coordination between contractors for our project as well as the utility companies and their crews.  With contractors needing to be spaced from one another by both time and distance, and there being a logical sequence in which the services get relocated, this is a hugely time-consuming process that will be ongoing throughout the winter in various locations.

The specific activities vary from corridor to corridor, involving different utilities and work at different stages of completion. Where hydro service is above ground, hydro relocations involve crews restringing the wires on the new poles once they’ve been installed in their new locations, and then removing the old poles.  Once the service is relocated on the new poles, crews then create the connections from the new service to individual addresses.

There’s also gas work underway in several areas along the vivaNext corridors, which involves relocating gas mains underground, and then attaching individual addresses to the new service.

And working in close coordination with the underground gas work are crews from the telecommunications companies, who are relocating their services into underground joint-use duct banks that the telecoms use. Constructing the duct banks involves much more work than simply stringing wires on poles, but the benefit is that with fewer poles along the side of the road there’s more potential to beautify the streetscape, which is an important objective for our project.

Finally, the last part of this complicated dance of roadside work involves our own crews who are busy relocating sanitary sewers and storm sewer systems and watermains.

All of this work is carefully planned out one step at a time and coordinated between our builder and the utility companies, then carried out in conditions that involve extra challenges due to the need to keep the ground warm enough to work in.  But it will be worth it, since the heavy road widening and construction is best done in the warmer weather.  And once it comes, we’ll be ready to go, widening the roads so that the rapidway stations can be installed.

So watch out for all the crews who are out there working this winter, and know that their work is an important part of the vivaNext schedule.

watching the transformation unfold

As you travelled on and around the busy corridor of Davis Drive last year, you undoubtedly noticed the significant construction activities underway. You may also be wondering what has been completed so far.

A lot of progress was made on the project this year and a number of milestones were achieved, all of which clears the way for the 2014 construction season. Nearly all retaining walls have been constructed, the eastern creek culvert has been replaced and extended, and the majority of hydro poles have been relocated. Road widening and base-layer paving has started, while reconstruction of Keith Bridge and the extension of the western creek bridge on the north side continue.

In addition, Parkside Drive was re-aligned with Longford Drive as a full four-way intersection. The re-alignment eliminated one set of traffic lights and improves overall traffic flow in the area.

We captured a number of these accomplishments on video and condensed them into a short clip for your viewing pleasure. The investment in modernizing our roads and revitalizing Newmarket’s infrastructure will go a long way to making sure Davis Drive is built on a solid foundation that will serve the growing needs of Newmarket for many decades to come. We look forward to building on the progress made and advancing the  bus rapid transit project bringing Viva service to Davis Drive. Thank you for your patience as we complete the transformation.

looking back at a busy year in vaughan

The transformation along the Vaughan Metropolitan Centre [VMC] corridor has begun. And 2013 was a busy year with vivaNext rapidway construction underway along Highway 7 West. Crews worked to remove signs, test soil and begin utility relocation to prepare for construction. Check out this video to see all the hard work that took place.

Although colder temperatures are here to stay, it doesn’t mean our work is done for the season. Throughout the winter, hydro, gas and telecommunications installations and relocations will continue, and we’ll also be busy with CN Bridge work on Highway 7.

Preliminary construction activity will also continue this winter in the second phase of vivaNext rapidway construction along Highway 7 West. This phase includes approximately 12 kilometres of rapidways on Highway 7 West from Helen Street to Edgeley Boulevard, and from east of Bowes Road to Yonge Street, including parts of Bathurst Street and Centre Street. During the winter months, you can expect to see contractors and surveyors walking along the corridor, reviewing designs, taking photos and gathering data.

The Toronto-York Spadina Subway Extension [TYSSE] project also celebrated a major milestone at the end of last year. In November, tunnel boring machines [TBMs] “Yorkie” and “Torkie” finished their tunneling journey north to VMC station. Together, these TBMs tunnelled over 6.4 km of twin tunnels for this project. Way to go! Take an inside look at TBM tunnelling for the project, including new footage of the inside operation of the TBMs and four separate TBM breakthroughs for the tunnelling in York Region.

When complete, this subway line will include six stops, 8.6 kilometres of track. Residents and visitors alike will enjoy the mixed-use, transit-oriented development offered in the VMC area, including convenient passenger pick-up and drop-off, a York Region Transit bus terminal, and connection to the viva rapidway running in dedicated lanes east and west along Highway 7. It will be a great place to work, shop or relax, and getting there will be easy whether you walk or ride transit.

Stay in touch with us over the winter! Coping with construction is a lot easier when you know what to expect, where, and for how long.  For an in-depth look at different elements of vivaNext projects, plans, designs and ongoing activities, visit vivanext.com and subscribe to receive construction notices for work happening in your area.

harsh winters can be a challenge

It takes a special kind of person to work in construction. Not only do they have to keep up with the physical demands of the job, they also have to deal with the elements including our hot humid summers and very cold winters.

Canadian winters can be very ruthless with high wind chills, heavy snowfalls, freezing rain and extremely cold temperatures. We’ve already witnessed all of the above this winter and Jack Frost has shown no signs of letting up as 2013 went out like a lion and 2014 came in much the same. If you ventured outside during the recent deep freeze, you know just how unbearably cold it can get.

Despite the inconvenience of the freezing temperatures, our vivaNext projects continue to move along. Our contractors brave the elements all year long in order to keep construction progressing to achieve the end result, a faster more convenient rapid transit system that will serve the public for generations to come.

For those of us already counting down the days until spring [70 to be exact], remember that in a few short months, the leaves will be unfurling and the tulips will be poking up through the ground. Nothing lasts forever, not even winters in Canada, although some days it feels like spring is an eternity away.

We look forward to warmer weather and sunny skies not only so we can get out and enjoy our short lived Canadian summers but also so the vivaNext construction projects can continue full speed ahead in ideal weather conditions.
