The Valley Line Light Rail Transportation (LRT) is a 27 km low-floor, urban line that will operate between Mill Woods in the southeastern neighborhood of the City of Edmonton and Lewis Farms in west Edmonton, Alberta. The project is being built in 2 stages: Valley Line Southeast and Valley Line West.
Valley Line LRT is owned by The City of Edmonton Infrastructure and AECOM is the owner’s engineer. Marigold Infrastructure Partners is a design-build joint venture agreement between Colas France and Parsons Canada. Parsons Canada is the Engineer-of-Record (EOR).
Valley Line Southeast (Downtown to Mill Woods)
Construction of stage one of the Valley Line Light Rail Transit (LRT) is connecting Mill Woods to downtown Edmonton with about 13.1 km of light rail transit. This stage includes 11 stops, an elevated station incorporating a transit center and Park & Ride, and a transfer point to the existing LRT routes at Churchill Square.
Valley Line West (Downtown to Lewis Farms)
The $2.6 billion Valley Line West project is a 14 km light-rail extension from 102 Street downtown to Lewis Farms. It is the second stage of the Valley Line and includes 14 stops and 2 stations: an urban-style, 27 km LRT line that will operate between Mill Woods in southeast Edmonton and Lewis Farms in west Edmonton.
Valley Line West LRT Design and Construction
Valley Line West LRT Construction Documents are developed based on the City of Edmonton’s
Infrastructure Specifications, which are consistent with the practices of Alberta Transportation (AT).
Carbon steel reinforcing bar CSA G30.18:21/ASTM A615 is used to reinforce concrete structures’
elements, and Stainless steel reinforcing bar ASTM A955 Grade 2304 Grade 420 is specified in the
exposed elements, such as brine splash zones.
During and post-pandemic, specialty materials procurement became a serious challenge for constructors due to shortages and increased mineral costs.
