92 Avenue Roundabouts

Al-Terra was retained by MLC Group to prepare a Concept Planning Study for Edmonton’s 92 Avenue between 215 Street NW and 231 Street NW. The scope of services included subsequent design and construction engineering services.

The 92 Avenue arterial road alignment was established through the Neighbourhood Structure Plans for the Rosenthal and Secord Neighbourhoods of the Lewis Farms Area Structure Plan. The alignment follows a pipeline corridor for the majority of its length between 215 Street and 231 Street, which was considered a constraint to the development of this arterial.

92 Avenue within the study area services primarily residential areas and included a large district park and school site along its frontage. Traffic analysis indicated that roundabout intersections and a two-lane roadway (one lane in each direction) would meet the long-term traffic demand for 92 Avenue west of 220 Street. The roundabout intersections for this roadway provide many intangible benefits in addition to providing equal or superior operations during peak hours. This project was considered an excellent candidate for roundabout intersections that not only provided a context sensitive design but are also considered a sustainable approach to arterial road design.

The plan developed was considered innovative as it achieved sustainability and improved operations while reducing overall construction costs. This project was jointly presented by the City of Edmonton and Al-Terra at the 2015 Transportation Association of Canada Conference in Charlottetown, P.E.I.
