Highway 417 Expansion
In 2002, MTO initiated a comprehensive operational review of Highway 417 (Ottawa Queensway) from west of Highway 416 easterly to Anderson Road (GWP 663-93-00) in response to growing traffic volumes in the City of Ottawa. This study evaluated opportunities to optimize the use of the existing facility, while providing for the efficient movement of people and goods. It examined existing and potential future problems and opportunities and provided a Recommended Plan to guide the evolution of the Queensway over the next 20 years. The study examined the mainline, as well as all interchanges and crossing roadways within the study limits. The Recommended Plan included widening Highway 417 from three to four mainline lanes in each direction from Highway 416 to Carling Avenue and from Metcalfe Street to Ottawa Road 174, among other recommendations.
The Preliminary Design and Environmental Assessment Study was carried out in accordance with the approved environmental planning process for Group ‘B’ projects under the MTO Class EA, and was documented in a Transportation Environmental Study Report (TESR) which received environmental clearance in 2008.
Highway 417 Bridge Replacements
Between 2004 and 2005, MTO completed a Preliminary Design and Environmental Assessment Study for the rehabilitation of Highway 417 bridges from 0.5 km west of Maitland Avenue to 0.6 km east of Island Park Drive. The purpose of this study was to evaluate the structural conditions of the bridges within the project limits; determine rehabilitation needs; develop plans to accommodate highway and City street traffic during the rehabilitations; review opportunities to address other deficiencies at the time of the rehabilitations; and address environmental impacts.
The Preliminary Design and Environmental Assessment Study was carried out in accordance with the approved environmental planning process for Group ‘B’ projects under the MTO Class EA, and was documented in a Transportation Environmental Study Report (TESR) which received environmental clearance in 2005.
The Recommended Plan included the deck replacement for 10 concrete deck / steel girder bridges and rehabilitation of the Merivale Road Overpass rigid frame bridges. Between 2007 and 2013, rapid replacement technology was used for the following bridge deck replacements:
- Island Park Drive bridges (Contract No. 1 completed in 2007);
- Clyde Avenue bridges (Contract No. 2 completed in 2008);
- Carling Avenue Eastbound bridges (Contract No. 3 completed in 2011); and
- Kirkwood Avenue and Carling Avenue Westbound bridges (Contract No. 4 completed in 2013).
The purpose of the current detail design project is to prepare the approved Preliminary Design concepts for implementation, including the widening of Highway 417 to four lanes in each direction from Maitland Avenue to Carling Avenue, and the associated widening and rehabilitation of the Merivale Road Overpass bridges which represents the last remaining contract as part of the Highway 417 Bridge Replacements.
