meet the NEW multi-use path on Highway 7 West

If you’re walking, strolling, jogging or cycling Highway 7 West in Woodbridge, there is a new multi-use path in the centre of the road to get you across the bridge over Highway 400. Watch our new video for a bird’s-eye view and a peek at what it’s like when you’re in it.

This protected path for pedestrians and cyclists has signalized intersections at each end to enable safe crossings back to the sides of Highway 7.

Separated from traffic and transit vehicles by concrete barrier walls on either side, the multi-use path is wide enough for two-way travel. By bringing travellers away from the outside of the bridge, as well as the busy ramps of Highway 400, the new multi-use path improves regular traffic flow, and crucially for pedestrians and cyclists offers an effective, convenient solution as people make connections to and from the Vaughan Metropolitan Centre and throughout Vaughan and York Region.

While centre-road travel for cyclists and pedestrians is a new concept here in York Region, they’ve been built in the U.S. and were originally inspired by the Sands Street Bikeway in Brooklyn, NY.

Integrated with the City of Vaughan’s bike lane program and York Region’s network of bike lanes, the multi-use path connects with raised bike lanes and wider pedestrian sidewalks west of Highway 400, from Famous Avenue to Bruce Street [raised bike lanes opening in 2020], and with bike lanes already constructed on Highway 7 from Edgeley Boulevard/Interchange Way to Bowes Road/ Baldwin Avenue, as well as up Millway Avenue to the subway and the newly opened SmartCentres Place Bus Terminal in the Vaughan Metropolitan Centre.

positive progress and multiple milestones reached >> year in review for Bathurst & Centre and Highway 7 West in Vaughan

watch our latest video to see some of the milestones from 2018

It was a year of sometimes messy construction on the Bathurst & Centre and Highway 7 West projects in Vaughan in 2018 – but a lot of positive progress was made and multiple milestones were reached! As you take a look at our year-in-review video, keep in mind, the vivaNext rapidway project is scheduled to open for service in these areas at the end of this year.

bridge expansion >> driving piles and pouring piers

When you go under a bridge, what do you see? Huge concrete columns – piers – that support it. The five-metre expansion of the bridge on Highway 7 West over Highway 400 is becoming fully visible as the new piers are completed. In the photo above you can see the three completed piers and crews pouring the concrete cap for the fourth.

Each one of these piers is held up with a set of nine piles. Piles are long poles driven straight down, until they reach a surface solid enough to hold everything above. In this case, the piles are each nine metres long.

In the photo, the tall piece of equipment beside the west abutment wall is the pile driver, which is – as you’d expect – used to drive the piles into the ground.

On top of the pile-supported-piers, there will be bridge footings, girders, and a wider deck to make room for cars and trucks – as well as buses on new vivaNext dedicated rapidway lanes and a multi-use path for pedestrians and cyclists.

While it’s true that piers are just a part of the bridge, the bridge is part of a road, which is part of a rapid transit system, which connects people to where they need to go.

Next time you go under a bridge, look at the piers that support it, and the engineering and construction that went into them.

We’re building rapid transit, and along the way making infrastructure – built to last.

Bridge Expansion Construction

the expansion of the Highway 400 bridge on Highway 7 West begins

Many of you have already noticed the work that has begun on Highway 7 West at the bridge over Highway 400, so here’s an overview of the components of the newest mega-feat of engineering that you’ll see happening over the next few years.

The project is part of the Highway 7 West rapidway project in Woodbridge-Vaughan and it will include expanding the bridge – with the new segment added to the north side – by approximately 5 metres.

New piers

Construction includes four new piers to support the expansion, which means new foundations, footing and forms. With multiple lanes above and below, this is a complicated project and safety is paramount for both the travelling public and the workers on site.

Huge girder lift

In September, the first piece of a gigantic girder will be lifted into place. This girder, which is needed to support the expansion of the bridge, will be installed in five pieces.

Multi-use path and rapidway

What makes this project especially remarkable, is that it will not only include dedicated red-asphalt bus lanes, but a pedestrian and cycling path will be constructed in the centre of the bridge between the bus rapidway lanes. Once complete, the bridge will provide roadway and connections for all types of transportation modes.

Realigned ramps

That’s not all. In addition, two of the ramps on the east side of Highway 400 will be realigned in order to accommodate potential future development. And to accommodate the waterway conditions in the area, new culverts will be built under the new ramps.

You’ll be hearing much more about this massive undertaking as time goes on. Next month, we’ll look more closely at what’s involved in expanding the bridge itself – think piers, pile drivers and parapets!

a look back at the CN MacMillan Bridge expansion

As work starts up on the Highway 7 bridge over Highway 400, which is being widened to accommodate rapidway lanes and a multi-use path, let’s take a look at a completed bridge expansion project: the CN MacMillan Bridge.

The Highway 7 bridge passes over the CN MacMillan Rail Yard, the second-biggest rail yard in Canada.

The expansion project, which was part of the Highway7 West-VMC rapidway project, involved widening the bridge by 8.5 metres to accommodate the two lanes of rapidway that opened in February 2017.

Crews poured 4,000 tonnes of concrete to build abutment walls, piers, foundation and piles, sidewalks and decks; embedded 300 tonnes of reinforcing steel; and built a new pedestrian sidewalk and hand-rail and bike lanes!

All of the work expanding the bridge had to be done – and was accomplished – without stopping the trains or impacting the 10 sets of tracks. For safety purposes, before construction even began, crews had to rehearse set-ups and take-downs with numerous safety drills so it would proceed like clockwork.

During construction, crews worked very closely with CN to coordinate work around train schedules. An additional challenge was the fact that the rail yard, which handles one-million-plus cars per year, also operates 24/7.

Mega feats of engineering and construction like the CN Bridge project are beginning again with the expansion of the Highway 7 west bridge over Highway 400. Next month, we’ll take a look at the different components of work involved for this project.
