Highway 15: Challenges

  • The reconstruction and widening of the federal section of Highway 15 presents a number of challenges

Highway 15

  • The federal section of Highway 15 will be widened from four to six lanes, including shoulders, to ensure fluidity and safety

Property Acquisition

  • In order to widen Highway 15 and bring it up to standards, some properties will have to be acquired, 0.3% of which are private properties
  • The permanent acquisitions are located on May and Gibbons streets in the Verdun Borough and on Île-des-Soeurs (C)
  • To ensure that NBSL project timelines are met, the Government must take possession of the properties in question by July 2015

Atwater Interchange – New Geometry

  • Full access to the Le Sud-Ouest and Verdun boroughs (at the request of the City of Montréal)
  • Improved safety of pedestrians and cyclists travelling between these two boroughs

LaSalle Boulevard – New Configuration

  • Two-way bike path and pedestrian walkways on each side of the boulevard
  • Link to the active transportation network running under the viaduct
  • Improved safety and comfort for pedestrians and cyclists

Gaétan-Laberge Boulevard – New Configuration

  • As part of the project, Gaétan-Laberge Boulevard will be extended northwards as an urban boulevard

René-Lévesque Boulevard, Île-des-Soeurs – New Configuration

  • René-Lévesque Boulevard will be moved
    • The bridge abutment will be on the bank of the St. Lawrence River, with a viaduct over the boulevard
    • The bike path will be retained and will run along the bank of the River

Île-des-Soeurs Tunnel – New Infrastructure

  • A pedestrian link passing under the Highway 15 structures is planned (access to an eventual station on Île-des-Soeurs for the LRT project)
  • This passageway will link Pointe Nord on Île-des-Soeurs with the rest of the island

Bike Path Network

  • The NBSL and new Île-des-Soeurs Bridge multi-use paths will connect with the City's existing bike path network
  • During the work, the private partner will be required to maintain the existing bike path network by means of detours and/or temporary structures
  • The NBSL multi-use path will include lookouts

Collaboration with the Selected Consortium

  • The selected consortium will have to demonstrate that the City and its boroughs have been consulted, and must make the necessary effort to take into account their feedback regarding the:
    • Traffic management and control plan
    • Urban integration plan
    • Landscape plan
    • Environmental management plan
    • Noise management plan
  • The selected consortium will be required to organize and/or participate in public information and discussion sessions

Traffic Management

  • The mandate of the TurcotNBSL Mobility Montréal committee, overseen by Mobility Montréal, is to:
    • Determine and coordinate the schedule of road work along the corridor
    • Facilitate decision making with respect to traffic management along the corridor
      • Determine which roads need to be closed, for how long, and the mitigation measures to be put in place
      • Ensure the dissemination of information during events that affect traffic
  • Committee members:
    • Infrastructure Canada
    • Quebec Ministry of Transport (MTQ)
    • City of Montréal and its boroughs affected by the project
    • Agence métropolitaine de transport
    • City of Brossard
    • The Jacques Cartier and Champlain Bridges Incorporated
    • Emergency service providers will also be represented on the Committee

Mitigation Measures – Noise

  • During the construction period, the following performance objectives will apply:
    Period Noise Level L10 in dBA
    7:00 a.m. to 7:00 p.m. (daytime) 75 dBA or ambient level during non-work plus 5 dBA, if greater than 75 dBA
    7:00 p.m. to 10:00 p.m. (evening) Ambient level during non-work plus 5 dBA
    10:00 p.m. to 7:00 a.m. (nighttime) Ambient level during non-work plus 5 dBA
  • Noise barriers will be installed to protect areas along Highway 15 identified as being sensitive
    • Vegetative barriers will be used whenever possible
    • When possible, the most bothersome activities (concrete drilling, intense trucking activity, etc.) will not be carried out near areas sensitive to noise

Mitigation Measures – Air Quality

  • The targeted performance objectives are as follows:
    • Total particulate matter (Ptot) = 120 µg/m3
    • Fine particulate matter (PM2.5) = 30 µg/m3
    • The chosen consortium must comply with the City of Montréal's Bylaw 90 pertaining to air purification
  • Planned mitigation measures:
    • In urban areas, streets used by vehicles and machinery will be cleaned daily
    • Dust-generating activities will be carried out in locations where the impact on the public is minimized


  • Environmental monitoring will be conducted in the sectors located on each side of Highway 15 during the work
    • Concerning noise and air quality
  • During the operational phase, air contaminants and noise levels will be monitored in populated areas
    • The permanent air quality station on Île-des-Soeurs will be operational as of February 2015

Next Steps

  • Consideration of feedback following the meetings
  • Ongoing collaboration with the City
