On schedule and under budget

Traffic is flowing smoothly both above and below the recently-opened 23 Ave interchange on Edmonton’s south side.

“The 23 Avenue interchange represents an essential investment in Edmonton’s transportation network,” says Mayor Stephen Mandel.  “By allowing motorists to move freely underneath 23 Avenue, we have improved the flow of traffic and created safe access to businesses in the area. We appreciate the assistance of the Province of Alberta in helping the city complete this key piece of infrastructure.”

The project finished on schedule and under the original budget of $265.7M, making the final cost $253.7M. This allowed the City of Edmonton to reinvest the $12M in savings into additional projects around the city, further improving the city’s transportation network.  The Province of Alberta contributed $235.8M to the project through the City Transportation Fund and the Alberta Municipal Infrastructure Program, while the City of Edmonton invested $13M. The remaining $4.9M was funded through the developer.
 
“This interchange is a shining example of how the province and municipalities work together to meet local needs and plan for the future,” says Alberta Transportation Minister Ray Danyluk. “The Government of Alberta invests in our communities by providing significant funding support for infrastructure projects. We are thrilled to have been a part of this important project.”

Features of the structure include:

  • A split diamond interchange with 23 Avenue going over Gateway Boulevard/Calgary Trail and the CP Railway, with Gateway Boulevard/Calgary Trail remaining at the existing elevation. The split-diamond configuration is an effective means of accommodating the high volumes of left-turning traffic at the intersection.
  • Retaining walls (instead of slopes) used to build the interchange ramps.
  • Noise walls for the southwest quadrant of the interchange.
  • Replacement of the at-grade signalized intersection at 19 Avenue with a grade-separated ramp. Northbound and southbound traffic have access but there will be no left-hand turn from 19 Avenue to go south on Calgary Trail.
  • Widening of 23 Avenue to six lanes (from 105 Street to Parsons Road).
  • A storm drainage tunnel to allow storm water conveyance and storage.
  • A multi-use trail along the north side of 23 Avenue in addition to a sidewalk along the south side. 

The intersection at 23 Avenue and Gateway Boulevard/Calgary Trail was rated as one of the busiest intersections in Edmonton with approximately 100,000 vehicles travelling through the intersection each day. The new interchange will better serve daily commute traffic, airport traffic, local business traffic, as well as transport truck, bike and pedestrian traffic.
