Queensway Expansion East

Highway 417 Nicholas Street Underpass (Site #3-224) Replacement, Detail Design

The Ministry of Transportation (MTO) has retained WSP Canada (WSP), to complete the Detail Design and Class Environmental Assessment (EA) for the replacement of the Highway 417 Nicholas Street Underpass (GWP 4048-11-00), in the City of Ottawa. Based on the findings of a Value Engineering Study undertaken by MTO in 2009, the scope of work involves the following:

  • Full replacement of the existing bridge on a new alignment immediately west of the existing bridge;
  • Re-alignment of the associated interchange ramps (specifically, ramps in the northwest, southwest and northeast quadrants) as required by the new bridge alignment;
  • Short extension of the fourth Highway 417 through lanes in each direction, to just west of the Nicholas Street Underpass; and
  • Construction of related works, including drainage, illumination, and roadside protection barriers.

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