Reconstruction of Grosvenor Avenue

Reconstruction of a portion of Grosvenor Avenue (between The Boulevard and Westmount Avenue).

About the Project

A project to rebuild the main aqueduct conduit under Grosvenor Avenue in 2023 presents the opportunity to address a number of infrastructure improvements in a concentrated area.

First, it is relevant to note that the section of Grosvenor Avenue between The Boulevard and Westmount Avenue touches a school zone. In the context of increased collisions in school zones overall, the City of Westmount is taking preventative action and introducing safer street design. Concretely, in the case of this project, this translates as the integration of permanent traffic calming measures to encourage pedestrian safety.

Second, the construction project will allow for reconstruction of the water main conduit, along with the replacement of all the household water service connections on public domain. The project also allows for reconstruction of the underground Hydro-Westmount infrastructure. Finally, it is an opportune moment to rebuild the street and sidewalks with improved design that addresses traffic mitigation and safety for all.

As part of Westmount’s Capital Works Programme, this project offers solutions in terms of safety, greening and sustainable development . Solutions for the benefit of the community. Consult the project details below.
