Queensway Expansion East

Project Overview

The Ministry of Transportation (MTO) has retained WSP | MMM to complete the Detail Design and Environmental Assessment Study for the proposed permanent closure of the Highway 417 Carling Avenue E-E On-Ramp (WP 4255-15-01) (on-ramp from Carling Avenue Westbound to Highway 417 Eastbound), in the City of Ottawa. The planned widening of Highway 417 between Maitland Avenue and Island Park Drive will result in operational and safety issues due to the introduction of a significantly substandard merge condition for the existing Highway 417 Carling Avenue W-E On-Ramp (on-ramp from Carling Avenue Eastbound to Highway 417 Eastbound). The permanent closure of the low volume E-E On-Ramp is proposed as a means to accommodate the planned widening of Highway 417 and provide a standard-length merge lane for the high volume W-E On-Ramp, while maintaining access to Highway 417 Eastbound within the Carling Avenue interchange.

The Highway 417 Carling Avenue E-E On-Ramp is a low volume on-ramp which carries one lane of traffic onto Highway 417 Eastbound. The project involves the following components:

  • Proposed permanent closure of the Highway 417 Carling Avenue E-E on-ramp;
  • Maintaining access to Highway 417 eastbound using the Carling Avenue W-E on-ramp, and providing a standard-length merge lane for the ramp;
  • Construction of related works, including retaining walls, illumination modifications / ATMS, and landscaping;
  • Implementing mitigation for redirected traffic from the closed E-E on-ramp, including:
    • Improvements at the Carling Avenue westbound / Kirkwood Avenue and Carling Avenue / Saigon Court intersections to facilitate safe and efficient access to Highway 417 eastbound for traffic being redirected to use the W-E on-ramp, and to address weaving issues at the Carling Avenue westbound / Kirkwood Avenue intersection associated with Highway 417 E-W off-ramp traffic (off-ramp from Highway 417 westbound to Carling Avenue westbound). These improvements include:
      • Two dedicated left turn lanes on Carling Avenue westbound at Kirkwood Avenue to accommodate left-turning traffic, including redirected traffic from the closed E-E on-ramp;
      • A raised concrete median island constructed between the through lanes and the left turn lanes on Carling Avenue westbound at Kirkwood Avenue to prevent E-W off-ramp traffic from weaving across Carling Avenue westbound to turn left on to Kirkwood Avenue southbound;
      • A dedicated left turn lane on Carling Avenue westbound at Saigon Court to accommodate traffic turning left on to Saigon, including redirected traffic from the E-W off-ramp seeking access to Carling Avenue eastbound / Kirkwood Avenue southbound;
      • Widening of Saigon Court by one lane to provide additional capacity;
      • New traffic signals at the Carling Avenue eastbound / Saigon Court intersection; and
      • New sidewalks and a segregated bike lane on Carling Avenue westbound.

Following the completion and approval of the Detail Design and Environmental Assessment study, there will be continued coordination with the City of Ottawa and local residents to develop and implement appropriate traffic calming measures on Coldrey Avenue to mitigate for any potential cut-through traffic which may result from the closure of the Carling Avenue E-E on-ramp.

Traffic management is being coordinated with the City of Ottawa and the proposed improvements have been designed to meet the City’s long-term objectives for the Carling Avenue corridor.

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

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.
