Description of projects

Over the past few years, projects on the Chaudière Crossing included the widening of the Hull Causeway and a major rehabilitation of the Union Bridge. These projects are scheduled for completion in fall 2024.

Hull Causeway widening

The Hull Causeway widening provided dedicated cyclist lanes and a wider sidewalk across the entire Chaudière Crossing. This work is part of a complete street concept that is in harmony with the Zibi development project and the remainder of the crossing. The cyclist lanes are now raised, and a new lighting system was installed, improving cyclist safety.

Union Bridge rehabilitation

The Union Bridge is a single-span steel truss. It has been in service for over 100 years. Several steel and concrete components were at the end of their useful lives and therefore required repair or replacement.

Impact on traffic

During the work, traffic may be impeded on an ad-hoc basis. Find out about lane reductions and closures on interprovincial bridges in the National Capital Region.
