Queensway Expansion East

Project Overview

Project Update (May 10, 2018): UPDATE on Highway 417 Widening and Rehabilitation from Maitland to Island Park Construction Contract, including Carling E-E Ramp Closure

  • The Ministry of Transportation would like to thank the public for its continued patience during the ongoing expansion of Highway 417 from Maitland to Island Park.
  • This extensive project, which will add one lane to the highway in each direction, rehabilitate the Merivale Road Bridge and make interchange improvements started in 2017 and should be completed in 2020.
  • As you are aware, this work included the closure of the Carling Avenue westbound ramp to Highway 417 eastbound coming from the Westgate Mall as of Monday, March 26 2018.
  • The ministry received approval from the Ministry of the Environment and Climate Change in February 2018 to move forward with the full closure of the ramp.
    • The permanent closure of this ramp will ensure that the Carling W-E ramp can be built to ministry standards, once construction is complete, and help merge traffic safely onto Highway 417 eastbound.
  • Currently, traffic is merging into the third lane on Highway 417 which is needed to ensure the safety of the workers at the Merivale Bridge.
    • Once construction is complete, motorists using this ramp will merge into the newly constructed 4th lane on Highway 417.
    • In the meantime, we urge you to please slow down and merge safely in this area.
  • As part of the full closure of the Carling E-E ramp, the ministry worked closely with the City of Ottawa on a plan to implement mitigation and traffic calming measures on City streets.
  • The ministry is working quickly with the City of Ottawa to complete the design and construct the necessary mitigation improvements.
    • There are many details to complete and agree on prior to moving forward, including utility relocations and intersection and traffic signal designs.
  • We encourage motorists to follow the signed detour to Kirkwood Avenue back to Carling eastbound and onto the Highway 417 eastbound ramp.
  • The current plan is to have the mitigation measures in place as quickly as possible. As a reminder, the future mitigation at Carling/Kirkwood/Saigon will include:
    • 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 south;
    • 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.
  • The ministry will also construct speed humps and other improvements on Coldrey Avenue to address concerns from City Councillors and the public.

Q & A:

1) Is the closure temporary or permanent?

Answer: The closure of the Carling E-E ramp is permanent. However, until the approved mitigation is in place, motorists should follow the existing detour around the construction zone to access Highway 417 eastbound.

2) Is there a detour?

Answer: Motorists should follow the signed detour which is from the ramp continue onto Carling westbound, take Kirkwood, back to Carling and on the Highway 417 eastbound ramp from there.

3) Why are there no other mitigations/traffic calming in place if the ramp is going to be closed permanently?

Answer: As part of the separate EA for the permanent closure of the ramp, mitigation measure will be put into place on City of Ottawa streets. However, since the ministry only just recently received EA approval, the design is yet to be completed. Once finished, MTO will work with its contractor to put the measures in place. The mitigation measures were not part of the original contract for the expansion of Highway 417 from Maitland to Island Park and will need to be added to the existing construction schedule.

4) Why can’t we add more signs about the upcoming mitigations so people have something to look forward to?

Answer: Given the level of construction activity through this area, space for additional signs is somewhat limited. As well, priority must be given to ensuring that the detour route is clearly signed. The ministry is working with its partners to provide updates to the public about the future mitigations to be built.


Project Update (March 21, 2018) – The decision letter from the Minister of the Environment and Climate Change in response to Part II Order requests is available here.


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.
