What impact will the work have on public transit?
Ultimately, the REM will run along the central median of Highway 10. Since this is where the reserved bus lane is currently located, this lane will need to be relocated gradually.
In early September 2018, a small 1-km stretch of the reserved bus lane on Highway 10 going west (Montréal) will be removed near the Highway 10/Highway 30 interchange. Buses will join the reserved lane a little further on, near the Malo and Leduc sectors.
In 2019, the central portion of Highway 10 will need to be isolated for the REM work. At this point, buses will not be able to use the bus lane. This transition will be carried out in stages.
New access ramps and reserved lanes for buses will be built so that public transit users will be moved unhampered between the Chevrier and Panama terminals and the Champlain Bridge. For example, starting in mid-September 2018, a new access ramp will be built near the Chevrier tunnel (before its demolition in spring/summer 2019).
While the construction of these new access ramps is designed to minimize impact on the South Shore bus service to and from Montréal, it is anticipated that travel times will be affected as of 2019. The planning of new bus traffic lanes is carried out in close collaboration with a number of partners, including such entities as transit authorities and Signature on the Saint Lawrence.
