Title | Addressing Geometric Design for the Highway 400 Widening and Anne Street Bridge Replacement Project: Designing around Temporary and Permanent Constraints |
Abstract or description | Undertaking the Highway 400 widening and Anne Street Bridge replacement project in Barrie, Ontario, within a confined urban setting posed various challenges. The original Highway 400 was constructed in the 1950s, with a two-span bridge over the highway at Anne Street. This project demanded innovative solutions to meet current transportation needs while considering future expansion plans.
To complete the highway construction, four stages were required to ensure that three lanes of traffic were maintained in each direction. In addition, the existing highway was designed for a 110 km/h design speed, where we were attempting to utilize a 120km/h design speed for staging wherever possible. However, due to the site constraints, a regulatory speed reduction to 80km/h was required as a 100km/h design speed was the maximum that could be achieved for the horizontal alignment in select stages.
