Construction Projects

Background 

The City of Cornwall will be rehabilitating culvert crossings at various locations throughout the city in 2025. Culverts are essential to our drainage systems.  

The rehabilitation process is called cured-in-place culvert lining. The process consists of inserting a flexible liner into the existing culvert. Once the liner is in place, steam is used to 'cure' or harden the liner. The process creates a new culvert inside of the existing one.

In 2025, the City will be replacing the culvert crossing on Marleau Avenue at Fly Creek. This culvert is essential to the Fly Creek drainage system.

The project involves removing the existing corrugated steel pipe (CSP) culverts and replacing it with a concrete box culvert. The existing culvert is in poor condition and needs to be replaced. As a result of poor soil conditions in the area, a helical pile foundation must be installed beneath the new box culvert.

In 2025, the City will be rehabilitating the twin barrel CSPA culvert that crosses Boundary Road at Marleau Avenue. This culvert is essential to the Fly Creek drainage system.

The project involves cleaning the existing culvert, installing new internal couplers inside the existing culvert, localized repairs to gabion baskets, and replacement of sections of guiderail. The existing culvert will remain in place and there are no anticipated changes or disruptions to the intersection of Marleau Avenue and Boundary Road. All work will be taking place inside the culvert and at the embankments at either end.
