Temporary Road Closures

Yonge Street Rail Bridge: Twinning for Double Tracking 

With GO service expanding to serve you better, Metrolinx is getting ready for double tracks along the Barrie Line.

Across the entire network, our goal is to deliver 6,000 train trips a week – with more frequent service, more stations, cleaner technology, and more connections. You won’t need a schedule because you’ll know that the next train will be coming soon. We’re transforming GO Transit to bring you more frequent two-way, all day service on the Barrie Line, up to every 15 minutes, seven days a week.

Construction on the Yonge Street rail bridge in Aurora (twinning to accommodate a second track) will be starting soon to help get you where you need to go, better, faster, and easier.

What is happening?

Metrolinx will be rebuilding the foundation and structure of the Yonge Street rail bridge in order to accommodate a second track along the Barrie Line. As part of this project, we will also be removing and restoring the sidewalks, fencing, landscaping, gutters, and existing utilities.

What does this mean for you?

Noise and vibration

This work will require the use of heavy construction machinery, and nearby residents may experience some noise and vibration as a result of the foundation work. However, to minimize disruption, this work will only take place during the day.

Lane closures

Motorists can expect rotating lane closures between Industrial Parkway and Allaura Boulevard for the duration of this work, beginning with the right northbound lane and then moving to the right southbound lane. Sidewalks below the bridge will also become unavailable for public use, but we will ensure that a safe route is provided for pedestrians under the bridge during construction.

Vegetation removals

There will also be vegetation removals to allow for this work to take place. Any time we have to remove trees, our plans are carefully studied by a qualified arborist and reviewed by our municipal partners and local conservation authorities. To learn more about our Vegetation Management and Tree Compensation Program, please visit Metrolinx.

Work hours

Working hours will be 7 a.m. to 6 p.m. - Monday to Friday. Weekend and overnight work will be minimal if required, and you will be notified of this ahead of time. We apologize for any inconvenience and will make every effort to minimize disruption.


If you have any questions or concerns about this work, please email us  at YorkRegion@metrolinx.com.
