HORSEHILLS CREEK BRIDGE REPLACEMENT

PROJECT OWNER: City of Edmonton
PROJECT LOCATION: 195 Avenue & 14 Street
PROJECT SCHEDULE: July – October 2017
PROJECT VALUE: $620,000

 

PROJECT DESCRIPTION:

This project involved the replacement of the existing bridge carrying 195 Avenue over Horsehills Creek in Edmonton and was part of a larger project that included intersection improvements at Manning Drive & 18th Street and upgrades along 195 Avenue. As such, the bridge division was a subcontractor to the Carmacks Municipal Division who was the General Contractor for the overall project. 

The scope of the bridge work included the removal and disposal of the existing single span 8.5 m precast girder bridge on treated timber substructure, and replacement with a new single span 10 m precast girder bridge on cast in place concrete abutments supported by driven steel h-piles. The bridge also included extensive rip rap armouring of the channel, concrete approach slabs and railing that comprised of thrie beam bridgerail that transitioned to w-beam approach rail with terminal impact attenuators. The deck was protected with a waterproof membrane followed by an asphalt wear surface and featured a super-elevated deck due to it being located on a curve. 

The project presented some unique challenges including scheduling, utilities, and environmental. The bridge work was scheduled to fit within the overall project schedule, avoiding conflict with ongoing roadwork on 195 Avenue and we coordinated with the utility companies to solve issues with overhead lines near the bridge. Due to the location of a designated wetland adjacent to the bridge, environmental protection was of utmost importance on this project. Using proper isolation techniques, we were able to complete the work with minimal environmental impact.
