Alert: Upcoming Weekend Closures of Hwy 400 at Finch Avenue West

As part of the Metrolinx Finch West LRT project, sections of the Highway 400 at the Finch Avenue West interchange will be closed for a second consecutive weekend, June 19-22, in alternating directions to allow crews to replace the Highway 400 Bridge in stages. 

The Highway 400 closures will be required from Friday at 10 p.m. to Monday at 5 a.m. 

During the first weekend of the closure (June 12-15, 2020), the southbound section of the Highway 400 Bridge were removed and then replaced with a new bridge deck and pre-cast steel girders. The northbound section of the Highway 400 Bridge will be replaced using the same approach this weekend (June 19-22, 2020). 

Prior to the planned weekend closures, there will be lane reductions on Finch Avenue West from 7a.m. on Thursday to 6 p.m. on Friday. Road closures of Finch Avenue West and of all Highway 400 on/off ramps at Finch Avenue will begin at 6 p.m. and continue to Monday at 5 a.m.

Mosaic Transit Group is using an innovative engineering technique called a Rapid Bridge Replacement (RBR) to replace the bridge, which will reduce the amount of time required for road closures from years to just two weekends and a few nighttime closures. Our crew reduced the impacts on traffic by constructing the new decks and installing the pre-cast girders in two nearby lots. 

The work site for the new deck installation will be on Finch Avenue West between Norfinch Drive/Oakdale Road and Signet Drive/Arrow Road below the Highway 400 bridge.
