Highway 417 Bridge Replacements and Operational Improvements

The Ministry of Transportation (MTO) has completed the Detail Design and Class Environmental Assessment (EA) Study for the replacement of 10 bridges (5 sites) on Highway 417 between Preston Street and Percy Street, as well as operational improvements on Highway 417 from Island Park Drive to Kent Street Overpass, in the City of Ottawa (GWP 4173-15-00). The project involves the following components:

• Replacement of the Preston Street Overpass, Rochester Street Overpass, Booth Street Overpass, Bronson Avenue Overpass and Percy Street Overpass structures using rapid replacement construction techniques;
• Preparation of temporary enclosed construction staging areas for the bridge replacement activities, including, construction of the new bridge structures;
• Construction operations on City streets to provide the rapid replacement equipment with access from the construction staging areas to the bridge sites;
• Demolition of 458 Catherine Street (former A1 Mini Storage facility) and construction of an earth embankment across the limits of the existing retaining wall at this site;
• Replacement of existing noise barriers on Highway 417 at the following locations:
  • On the north side of the highway, from Island Park Drive to east of Parkdale Avenue;
  • On the north side of the highway, from the Rochester westbound on-ramp, east to Bronson Avenue;
  • On the south side of the highway, from Island Park Drive to west of the CPR/O-Train Overpass;
• Implementation of Queensway Context Sensitive Design recommendations related to structural design elements, noise barrier design, fencing, and landscaping, where applicable;
• Construction of related works including: tall wall median concrete barrier and drainage improvements from the CPR/O-Train Overpass to the Kent Street Overpass; retaining walls; illumination; overhead and ground-mounted signage; utility relocations; and roadside protection, as required; and
• Coordination of construction activities with the following two MTO Detail Design and Class EA studies:
• WP 4089-07-01 Bronson Avenue Interchange Improvements; and
• GWP 4057-12-00 New Noise Barrier Retrofits.

Traffic management and pedestrian/cyclist detours for construction staging has been coordinated with the City of Ottawa.
