Construction of the Valley Line West LRT is in full swing in the city of Edmonton, and Marigold Infrastructure Partners has many milestones to look forward to in the new year. Marigold teams will be continuing with construction activities over the holidays.
To accommodate the LRT, vehicles, pedestrians and cyclists, a new bridge crossing Groat Road on Stony Plain Road is required. Demolition of the current bridge will take place at the end of 2022, and construction of the new bridge will commence in the new year. When complete, the new Stony Plain Road bridge will help improve access between downtown and west Edmonton for years to come.
Features of the New Stony Plain Road Bridge
The new Stony Plain Road bridge will feature one lane of vehicle traffic in either direction, the Valley Line West LRT tracks, a sidewalk for pedestrians, and a shared-use path running along the south side of the bridge. Demolition of the current bridge will take four days, and construction of the new bridge is estimated to take up to two years.
Demolition of the current bridge will be done in parts, firstly to remove the asphalt, guardrails, and concrete debris, followed by removal of the girders and piers. Heavy equipment and machinery will be used to remove the bridge deck, load out the concrete debris, and remove and transport the piers and girders.
Duration of the Demolition
Demolition of the current Stony Plain Road bridge will occur during daytime and overnight hours from 7 p.m. on December 29, 2022, to 6 a.m. on January 3, 2022.
The work will require:
- a short-term closure of Groat Road between 107 Avenue and River Valley Road (Dec. 29, 2022, to Jan. 3, 2023)
- a long-term closure of Stony Plain Road between 129 Street and 131 Street (Dec. 29, 2022, to fall 2024)
- a second short-term closure of Groat Road between 107 Avenue and River Valley Road to install the new bridge (more details to follow in spring 2023)

Demolition of the bridge is scheduled to take place over the New Year long weekend to reduce impacts to the public. Groat Road between 107 Avenue and River Valley Road will be closed to all vehicles and pedestrians for four days.
Traffic and Pedestrian Detours
During the demolition of the Stony Plain Road bridge, a few detours are set in place to ensure public safety.
All vehicle traffic will be redirected to either 102 Avenue or 107 Avenue, as Stony Plain Road will be closed between 129 Street to 131 Street from 7 p.m. December 29, 2022, until fall 2024. Groat Road between 107 Avenue and River Valley Road will also be closed for the duration of four days, from 7 p.m. December 29, 2022, to 6 a.m. January 3, 2023.
With the demolition of the Stony Plain Road bridge taking place starting December 29, 2022, all pedestrian access across the bridge will be closed until fall 2024. Eastbound and westbound pedestrian access across Stony Plain Road Bridge will be detoured to 102 Avenue or 107 Avenue until the new bridge is constructed and re-opened in fall 2024.
Northbound and southbound pedestrian access on Groat Road will be detoured to Ramsay Ravine, near Government House Park, over the New Year long weekend when the bridge demolition takes place (December 29, 2022, to January 3, 2023).
Impacts on Public
While demolition and construction will take place primarily during daytime hours, some overnight work may be necessary. Due to the use of heavy equipment, noise and vibration can be expected; however, Marigold will make every effort to reduce impacts on the public.
