Bridges along Groat Road are undergoing rehabilitation with anticipated completion in fall 2020.

River Valley Road under Groat Road Bridge Closure

From January 20 to February 15, 2020, River Valley Road and the shared-use path under Groat Road Bridge will be closed to all vehicle and pedestrian traffic. During this time, the 40-tonne gantry cranes will be used with concrete saws to demolish the concrete bridge deck and girders directly above River Valley Road and the pedestrian walkway.

Completion of this work will bring the project into the second phase of the Groat Road Bridge rehabilitation. The heaviest piece of a cast-in-place concrete girder that will be demolished will weigh close to 80 tonnes and will require both gantry cranes to remove.

Due to this work being completed directly above the road and shared-use path, it will not be safe for the public to travel underneath the bridge until this stage of demolition is complete.

Pedestrian and cyclist access to the bridge will be maintained on the northeast side. Pedestrians and cyclists approaching from the northwest must find alternate routes. Signage in the river valley and trail system has been installed, warning of the closure. Additionally, cyclists are permitted to ride in the road.

We thank all travellers for their patience as we move into the next phase of this project.

Pedestrian and Cyclist Access

The access points for the sidewalk remain the same as before. Large concrete barriers have been installed on the west of the sidewalk to separate pedestrians from traffic, and fencing along the east keeps the sidewalk separated from the new construction site. Due to the narrow width, cyclists must continue to dismount while using the sidewalk or ride along the bridge deck.

Additionally, due to the proximity to the construction site, pedestrians and cyclists who dismount will occasionally be signaled to stop at the discretion of flag persons in order for equipment to move into and out of the new job site on the east side of the bridge.

All users are urged to use caution and to watch for traffic at either end of the bridge deck when accessing the temporary sidewalk. Please refer to the map for further details.

Future Closures

Future closures are expected through the duration of the project and are expected to proceed as follows:

River Valley Road Impacts

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. Bridges along Groat Road are undergoing rehabilitation with anticipated completion in fall 2020.

Project Timeline

Construction - spring 2018 to fall 2020

Pre-construction Information Session - March 2018

Tendering Period - November to December 2017

Detailed Design - completed October 2017

Preliminary Design - completed November 2016

Field Investigation - As part of the permitting process for this project, the Project Team completed a field investigation in spring 2017 to determine if historical or archeological artifacts are present in the key portions of the project area.

Project Details

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.
