Stagecoach Road Bridge Culvert Replacement

Project overview

July 2016

Project description

The City of Ottawa is undertaking the preliminary and detailed design for the renewal of the Stagecoach Road Bridge Culvert (SN882380) over the Herbert Municipal Drain in Osgoode Ward. The project location is situated on Stagecoach Road approximately 250m south of Snake Island Road. The existing bridge culvert has reached the end of its service life and is in need of replacement. The City has identified the need for reconstruction of the following works:

  • Replacement of the existing open footing concrete box culvert (1940s construction), with a comparable 3.0m wide, by 1.8m high precast box culvert.
  • Placement of a distribution slab on top of the box culvert.
  • Construction of curbs, headwalls, and cut off walls.
  • Gabion wall construction for slope stability
  • Guiderail installation to meet current design standards.
  • Minor ditching and erosion protection measures.

Public notification and involvement

The bridge culvert project is an end of service life replacement of a critical piece of infrastructure that is required to maintain the level of service of the roadway network in your area. As such notices will be provided to residents affected by the bridge construction, and the traffic detour in advance of the construction. Public Variable Message Signs (PVMS) will be posted in advance of the construction to notify motorists of the impending road closure.

Construction notice (August 2016)

Beginning by Mid September 2016, the City of Ottawa will begin bridge construction work in your area.  This work is being conducted to replace an existing bridge culvert that has reached the end of its effective service life.

Where: The bridge culvert is located on Stagecoach Road, 250 meters south of Snake Island Road within the Osgoode Ward.

What: The City of Ottawa will be conducting a full replacement of the bridge culvert, with a distribution slab, new curbs, guiderail installation, as well as frost tapers, and asphalt reinstatement. Minor ditching work and erosion protection measures will also be performed.

Why: This work is necessary due to the age and condition of the existing structure, which was built in the 1940s and rehabilitated in the 1970s. The structure has reached the end of its service life and requires replacement.

When: The bridge rehabilitation is expected to commence mid-September 2016 and extend into late-Fall 2016.

Who: The Contractor, Colautti Construction Ltd., will be performing the construction for the City of Ottawa.


Accessibility is an important consideration for the City of Ottawa.  The City makes every effort to provide access through and around construction sites.  If you require special accommodation, please contact the On-Site Inspector or the Contractor’s representative.


Due to the nature of the repair work and the narrow width of the roadway, a full road closure is required to facilitate this replacement. A detour will be posted to provide direction to area motorists.  The public is reminded to exercise caution around the work zone.  The City appreciates your patience as we conduct this important renewal work.
