Until October 31, 2019, one lane in each direction of the Emily Murphy overpass over Groat Road will be closed for the second phase of bridge rehabilitation. The eastbound exit from Hawrelak Park will need to exit south onto Groat Road. Park and golf course access will be maintained on the west side.
Project Update - Fall 2019
Several project milestones were achieved over the summer including demolition completion and girder erection. We are nearing completion of the rehabilitation of the west half of the bridge. Work continues on Emily Murphy Park Road over Groat Road Bridge and is expected to be substantially completed this year.
Intermittent closures are expected until the end of the September and into the remainder of the year as the west side of the river bridge is completed, adjacent roadwork wraps up for the season and the Emily Murphy Park Road over Groat Road bridge is completed and work shifts to the east side of the bridge.
Obey signage in the area. Updates will be posted on social media and with 311.
Future closures are expected through the duration of the project and are expected to proceed as follows:
Superstructure Demolition- Winter/Spring 2019 & Winter/Spring 2020
Demolition of the northernmost portion of the existing bridge superstructure will take place over River Valley Road. This demolition work is completed utilizing a large land-based crane to disassemble the end span of the bridge; due to the footprint of the crane and the risk associated with hoisting heavy loads in excess of 100 tonnes, River Valley Road will be closed for the extent of these particular demolition operations.
Girder Installation - Spring/Summer 2019 & Spring/Summer 2020
Following the demolition of the existing bridge superstructure, new steel bridge girders will be installed as the first step in the reconstruction of the bridge. Installing the bridge girders on the northernmost portion of the bridge will require closures of River Valley Road in order to ensure the safety of the traveling public as loads of up to 80 tonnes are hoisted over the road and secured into place.
Bridge Abutment Reconstruction - Winter/Spring 2019 & Winter/Spring 2020
During reconstruction of the north bridge abutment located on the north edge of River Valley Road, it may be necessary to implement short-duration road closures for logistically-restricted construction operations, such as major concrete pours. These restrictions will generally be short duration and limited in nature.
Bridge Deck Reconstruction - Spring/Summer 2019 and Spring/Summer 2020
Major concrete pours that are required for reconstruction of the new bridge deck will require full closures of Groat Road Bridge due to spatial constraints and to ensure long-term construction quality. These concrete pours will occur during nighttime hours to minimize impacts to commuters.

About the Project
In 2018, the City began the rehabilitation of 3 Groat Road bridges and Groat Road from 87 Avenue to the North Saskatchewan River.
Groat Road Bridge over the North Saskatchewan River
The Groat Road Bridge over the North Saskatchewan River was constructed in 1955. The last major rehabilitation of this bridge occurred in 1989-1990. Rehabilitation will extend its service life by at least 50 years and improve the functionality of the existing sidewalk by widening it to shared-use path standards.
Groat Road Bridge over Victoria Park Road
The Groat Road Bridge over Victoria Park Road was constructed in 1954. The bridge is generally in good condition but currently requires a wearing surface replacement, new deck joints and other miscellaneous repairs.
Emily Murphy Park Road Bridge over Groat Road (Mayfair Bridge)
The Emily Murphy Park Road over Groat Road bridge was constructed in 1963. The bridge is generally in good condition but requires some minor rehabilitation to extend its service life until more substantial rehabilitation work is needed in 10 years or more. Additionally, the north sidewalk will be widened to shared-use path standards.
Roadwork
Groat Road from 87 Avenue to the Groat Road Bridge over the North Saskatchewan River, including the ramps at Emily Murphy Park Road/Bridge and Hawrelak Park, will be renewed as part of this project. Work is anticipated to be complete by 2020.
The sidewalks on the east side of the ramp from Emily Murphy Park Road and from the Mayfair Bridge to Hawrelak Park will be widened to shared-use path standards.
