Project Update - September 7, 2018

The project team, in collaboration with industry experts, evaluated the length of construction if the bridge is closed entirely, however it was determined that given the scope of work required, the overall construction duration would not be substantially shortened by this option. Maintaining one lane in each direction is a balance between construction duration and river crossing access to vehicle and pedestrian traffic in the area.

In order to complete rehabilitation on the Groat Road over Victoria Park Road Bridge, traffic on Groat Road northbound must be reduced to a single lane to provide work space for the Contractor. The project team installed a new temporary signal light at the intersection of Groat Road northbound and River Valley westbound to regulate the merging traffic north of the intersection. It is expected that construction on the Groat Road over Victoria Park Road Bridge will be completed by the end of October 2018, at which time the temporary signal at the north end of the bridge, which is causing congestion later in the afternoon, will then be deactivated to resume the free flow of traffic on Groat Road northbound lanes.

All work done to date on the Groat Road river crossing was to move traffic to the east side of the bridge giving the Contractor the west half to work on. A Gantry crane is being installed that will begin removing the existing deck and girders starting in November, once this demolition of the west half is complete new girders will be installed starting in February 2019 which will be followed by pouring of a new deck starting in May 2019. When the west half is complete traffic will be placed on the new side and the entire process will be repeated on the east half of the bridge. Project completion is fall of 2020 and this bridge river crossing will be one lane in each direction for the duration of the project.

Pedestrian and cyclist traffic is currently being accommodated on the east sidewalk of the river bridge. This former shared-use path has been reclassified as a sidewalk through the duration of this construction due to the narrowed travel width. This sidewalk has been signed for cyclists to dismount or continue to travel on the roadway. The project team thanks cyclists for their cooperation in dismounting and sharing this river crossing space with all modes of transportation.

Additionally, the City project team is proactively working with the Contractor to devise an optimum strategy for enhanced snow removal on the river bridge during the winter seasons.

About the Project

The City of Edmonton is undertaking the rehabilitation of three Groat Road Bridges and Groat Road from 87 Avenue to the North Saskatchewan River beginning in 2018.

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 completed 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.
