Bold plan announced to transform Montreal expressway with riverside cycle paths and more

The project aims to enhance Montreal’s infrastructure, addressing evolving needs in traffic flow, goods transportation, and active mobility, while significantly improving the living environment for the community.

Constructed in 1966, the non-elevated lanes of the federal section of the Bonaventure Expressway have reached the end of their service life, necessitating reconstruction. The reconfiguration will maintain the current three-lane capacity in both directions through a 2+1 configuration with dynamic management of the third lane. Serving as a crucial freight transportation corridor with 20 million trips annually to the Port of Montreal, the transformed expressway will not only meet commercial demands but also prioritize effective and safe mobility for all users in alignment with sustainable development principles.

Active mobility

The forthcoming boulevard will see a strategic shift as traffic lanes are repositioned away from the shoreline, coinciding with the removal of Carrie-Derick Street. This dual move not only diminishes the road footprint but also slashes heat islands by an impressive 40%. As a result, a riverside expanse will be liberated, paving the way for the creation of a lush green corridor boasting exclusive active mobility paths. A nearly 2.5-kilometer pedestrian promenade and a versatile multipurpose path will seamlessly link with existing pathways in the vicinity.

Montreal expressway green plans

In addition to the infrastructure improvements, the Montreal expressway project aims to enhance the overall aesthetics and biodiversity of the corridor by planting 650 trees, 18,000 shrubs, and 13,000 perennials. These landscaping features will contribute to reducing heat islands and protecting biodiversity.

Furthermore, JCCBI, the entity overseeing the project, is committed to addressing environmental concerns in the sector. Plans include implementing measures for biodiversity protection and soil management, building on the success of the Solution Bonaventure project initiated in 2016. This initiative has played a vital role in containing and treating contaminated groundwater, contributing to the protection of the St. Lawrence River.

A new gateway

“This signature project will finally reconnect the metropolis to the St. Lawrence River! Transforming a highway to bring it into the 21st century is a major project that doesn’t come around often and we seized the opportunity to ensure safe travel for all users,” said Plante. “This new gateway to the city will directly contribute to Montreal’s attractiveness and the quality of life of residents of the area for generations to come. This is the result of a great collaboration with various partners, with whom the City of Montreal was able to fully share its expertise and its audacity.”

To ensure safe movements within the newly configured boulevard, the speed limit will be reduced from 70 km/h to 50 km/h, with additional traffic lights. The construction is scheduled to take place from 2025 to 2029, during which two traffic lanes will be maintained in both directions.

The comprehensive Montreal expressway project reflects a collaborative effort with various partners, aligning with the City’s vision of sustainable development and contributing to the city’s attractiveness and the quality of life for residents for generations to come. Further details on the project will be available in early 2024.
