REM crossing over Highway 40 starting October 6
Date: October 6 to 26, 2019*
Schedule: Nights only, except the weekend of October 19-20
Where: Highway 40 at Henri-Bourassa Boulevard West
Nature of work
To allow the REM’s elevated structure to be built on the West Island, traffic obstructions are planned starting October 6 on Highway 40 (A40) where it meets Henri-Bourassa Boulevard. During this operation, the REM deck will be installed above Highway 40. This “big span” operation will be done in multiple phases over a period of about one month (from October 6 to 26).
Work will be done only at night, except for the weekend of October 19 and 20 when daytime work will also be done. During the day, all roadways will remain open to traffic and users will be able to travel safely under the structure.
Anticipated impacts and mitigation measures:
Segments of Highway 40 and the service roads are scheduled to be closed in the area as the installation of the REM crossing progresses above the highway.
October 6 to 10 *: Nighttime closure of the westbound service road
– 8 p.m. to 5 a.m.: Closure of the Henri-Bourassa Blvd. access ramp leading to the A40 West service road
– 10 p.m. to 5 a.m.: Closure of a segment of the westbound service road at Henri-Bourassa Boulevard
– Detour via Hymus Boulevard, up to Des Sources Boulevard and then back on to the A40.
– The A40 will be open during that period. However, please note that on October 9 and 10, the right lane of the A40 West will be closed from 10 p.m. to 5 a.m., which may cause slowdowns.
October 11 to 26*: Monitor work progress on the REM website
To monitor work phases and any detours that may be set up after October 10, please go to the REM website at rem.info/en/works-info. The information will be updated with complete details as the work progresses.
October 19 and 20*: Daytime closure of eastbound Highway 40 for the entire weekend
During the weekend of October 19 and 20, a segment of the A40 East will be closed (A40 West will remain open). As a result, travel may be more difficult on A40 East that weekend. We recommend that users choose Highway 20 instead.
Details about the obstructions and detours will soon be available on the REM website at rem.info/en/works-info.
* Planned dates are subject to change according to work progress and weather conditions.
In order to limit the impacts on road traffic, a very effective technique will be used on the West Island: a launching beam. This is the first time launching beams have ever been used in Québec.
Each one is 105 metres long and can support up to 550 tonnes!
These heavy-duty beams are placed between two REM columns. The prefabricated segments of the elevated structure (weighing about 50 tonnes each) are then lifted and moved into place against one another to form the deck on which the REM’s rail cars will run.
Two launching beams are used to build the REM’s 14.5-km Airport and Sainte-Anne-de-Bellevue branch. In October 2019, launching beam Marie will cross Highway 40.
