The purpose of this project was to undertake the Detail Design for the Highway 417 (Queensway) Bridge rehabilitations.
The project has met the requirements of the Ontario Environmental Assessment Act (OEAA) for this type of project.
The main components of this project will address issues such as:
- Maintaining a safe and efficient transportation system;
- Reducing traffic congestion and delays, and
- Improving existing infrastructure. Such improvements includes:
- Replacing decks and beams and repairing the abutments and wing walls for 10 thin slab bridges, using rapid replacement technology;
- Pavement rehabilitation;
- Install retaining walls to accommodate traffic detours;
- Lower city roadways to provide vertical clearance under the widened bridges;
- Construct Advanced Traffic Management Systems (ATMS). ATMS on Highway 417 is; an integrated system of various electronic tools intended to optimize the capacity of the highway and, provide a satisfactory level of service to the motoring public within the traffic lanes available. Electronic vehicle sensors embedded within the pavement supplemented by visual verification through a Closed Circuit Television Network provide faster detection and response to incidents and congestion along the highway. Portable variable message signs and links to the media provide timely dissemination of current traffic conditions to the traveling public to assist in making informed decisions of route selection and travel time requirements.
- Replace existing median barrier with new concrete barrier where appropriate;
- Update existing and implementing new illumination, and reinstate traffic signals;
- Existing drainage will be modified to accommodate lowered city roadways, replacement of existing median barriers, and construction of new retaining walls, and
- Update existing signage and install barriers where appropriate.
The Transportation Engineering Principles, undertaken for this project, ensure that the project provides for a safe and efficient transportation system.
