**POSTPONED** Temporary closures - weekend of January 17 - A-13 / A-40 interchange

Highway 13 and 40 interchange in Montreal (Saint-Laurent borough)

**The temporary closures scheduled during the weekend of January 17th, 2020 have been postponed. New date to be confirmed.

The ministère des Transports advises road users that temporary closures will be required in the interchange area of ​​highways 13 and 40. The overpass on Highway 13 southbound will be dismantled, which will require, among other things, the complete closure of Highway 40 and its service roads in both directions.

Traffic management

Highway 13 southbound 

• Complete closure between exit 6 - A-40 / Quebec / Ottawa / Gatineau and the entrance from highway 40 eastbound, from Friday, January 17 at 11:00 p.m. to Monday, January 20 at 5:00 a.m.

Highway 40 and service roads in both directions

• Complete closure in the exchanger sector, from Friday, January 17 at 11 p.m. to Monday, January 20 at 5 a.m.

Detours will be marked with temporary signage. Road users will, however, be requested in the sector and favour optional routes, for example highways 20 and 30 on the South Shore, or even highway 15 (Décarie and the Laurentides) and highways 440 or 640. Congestion episodes are to be expected.

In the event of unfavourable displayed conditions or operational constraints, this work could be postponed or cancelled.

In order to adequately plan your trips, find out about current and future obstacles by consulting the Québec 511. This project is included in the 2019-2021 list of road investments in the Montreal region. The ministry thanks road users for their cooperation. For the safety of road users and that of workers, compliance with the signs in place is essential.

Environmental mitigation measures :

The REM project aims to integrate harmoniously with its immediate surroundings, which is why more than 85% of the work will be carried out on public domain, on existing road and railway rights-of-way. At the same time, however, some brush clearing and deforestation work will be realized in two sequences, before March 1st and after August 15th, which are necessary so the REM rail infrastructure, stations and access roads can be constructed. In the next few weeks, branch removal and tree and shrub cutting will take place in your sector.

Mitigation measures :

  • Work will be performed outside the nesting season (March 1st to August 15th)
  • These activities will be supervised and coordinated by our environmental experts, and will follow industry best practices and applicable standards and regulations;
  • At-risk plant species and trees will be relocated;
  • Through a reforestation program, the same number of trees that were cut in temporary construction zones will be replanted, and an additional 10% will be planted in the municipal territory or borough where the trees were cut.
