The Ministry of Transportation (MTO) has retained WSP to complete the Detail Design and Environmental Assessment Study for the rehabilitation of four bridges along Highway 417 (GWP 4074-11-00), in the City of Ottawa.

A Notice of Study Commencement was published for this Detail Design study in November 2019, which included the widening of Highway 417 by one lane in each direction from Aviation Parkway to Hunt Club Road, along with the rehabilitation / replacement of various bridges and structural culverts along the corridor.  
​
In 2021, the MTO made the decision to take a staged approach to complete the work within the limits initially identified for the project. 

The scope of work for this project includes the following:

• Rehabilitation of the Highway 417 Aviation Parkway Off-Ramp (NBL) and Highway 417 Aviation Parkway On-Ramp (SBL) Overpass Bridges;
• Rehabilitation of the Highway 417 Aviation Parkway Overpass “Y” Bridge;
• Rehabilitation of the Highway 417 Walkley Road Underpass;
• Construction of a noise barrier in the vicinity of the Highway 417 westbound (WB) to OR 174 eastbound (EB) ramp; and
• Construction of related works, including pavement rehabilitation, drainage improvements, modifications to illumination/ATMS and landscaping.

​The remainder of the works identified in the November 2019 Notice of Study Commencement will be addressed under separate Detail Design and Class Environmental Assessment studies to be undertaken at a future date. This website will continue to be updated to include information on the remaining projects as they occur.

Please also note that the GWP number for this project has changed to GWP 4074-11-00 (newspaper notices published in November 2019 referenced two numbers, GWP 4074-11-00 and GWP 4099-11-00) and that all future correspondence will reference the new number.

The Detail Design for the structural rehabilitations is based on a separate 2016 Preliminary Design study (GWP 4074-11-00) that identified a long-term management plan for bridges and culverts within the study area.

This study is following the approved environmental planning process for Group ‘B’ projects under the MTO Class Environmental Assessment (Class EA) for Provincial Transportation Facilities (2000), with the opportunity for public input throughout the project.

This website will be updated regularly, providing project and schedule updates, information on upcoming events such as the Public Information Centre, as well as project documentation as it becomes available.
