102 Avenue over Groat Road - Bridge Replacement Project
Girder Stabilization & Groat Road Closure
At approximately 2:15am, March 16, four of the seven steel girders required for the 102 Ave Bridge Replacement buckled during installation. Public and worker safety required immediate ongoing closure of Groat Road, a major arterial roadway that approximately 42,000 vehicles use on any weekday. The City worked with its contractor to establish a three-week strategy to stabilize the girders and re-open Groat Road.
The City is on track to meet its Week 2 goals for girder stabilization.
Transferring the girder weight onto support cranes has led to minor improvement in the overall girder alignment. The contractor continues to brace the existing girders and will soon install the seventh girder to help stabilize the overall structure. Installing the seventh girder is necessary to achieve overall bridge stability and is not a permanent solution.
Once the seventh girder is installed, the City and its contractors will begin evaluating the overall structure stability to determine whether the girders must be repaired or replaced and what this means for the overall project.
Once the girders have been stabilized Groat Road can be safely re-opened. The City is still on track to re-open Groat Road on or before April 7; however further disruptions of Groat Road will be needed for ongoing 102 Ave Bridge work.
The City of Edmonton appreciates the patience and understanding of all residents as we work to resolve this situation.
Groat Road traffic will continue to detour to Victoria Park Road, 149 Street to Whitemud Drive and 109 Street to the High Level Bridge. Motorists are reminded to give themselves extra time to get to their destinations.
Parking restrictions remain in effect until Groat Road reopens along:
- 116 Street from 100 Avenue to Jasper Avenue, east side.
- 124 Street from Stony Plain Road to 107 Avenue. Daytime, nighttime and weekend parking is permitted on both sides. This location will remain as AM/PM peak hour ‘no parking’ (6am to 9am and 3:30pm to 6:30pm Mon-Fri) until Groat Road re-opens.
- 124 Street from 107 Avenue to 111 Avenue on the west side: AM/PM peak hour tow-away zones in effect.
Traffic Signal Changes
Traffic signals have been adjusted to mitigate increased traffic on:
- 116 Street at 100 Avenue to have longer green lights for peak hours.
- Groat Road/107 Avenue and Groat Road/111 Avenue intersections to improve east/west traffic due to decreased north/south traffic.
- 107 Avenue at 117 Street and 116 Street have longer green lights for afternoon peak.
- 124 Street north of 104 Ave, more southbound time for peak AM traffic
Traffic Operations will continue to monitor and adjust the signals as necessary.
Roadside messaging has been updated along existing detour routes and has expanded to include 109 Street, Whitemud Drive and Yellowhead Trail.
March 2 - Parking Restrictions on Stony Plain Road
Due to increased traffic there will be ‘no stopping’ on the south side of Stony Plain Road west of 124 Street weekdays from 6 am-6 pm. Parking meters will be available after 6 pm and on weekends. These changes will remain in place for the duration of bridge construction.
Pedestrian & Cyclist Trail Closure - Starts February 18, 2015
Starting on February 18, the Groat Road shared-use path from 107 Avenue to Victoria Park Road will be closed for eight weeks.
Closures & Detours
Road Closures and Detours Map
During the bridge replacement construction, several road closures will be required to accommodate the construction activities. To assist those affected by these closures, an interactive map has been created which will be updated to provide the latest closure and detour information.
About the Project
The 102 Avenue over Groat Road Bridge serves as a major east/west corridor into and out of Edmonton's downtown. Constructed in 1910, the bridge has reached the end of its lifespan and will be demolished and replaced with a new bridge to better serve Edmontonians.
The replacement bridge has a clear span of approximately 100 m and will maintain the existing four-lane configuration. It is designed to accommodate two 2.1 m wide bike lanes on the road shoulder and 2.2 m wide sidewalks along the north and south sides. The design of the new bridge considers:
- Stabilization of both the east and west slopes using soil nails.
- Maintain the existing four-lane configuration with wider lanes to meet current standards.
- Concrete deck with asphalt surfacing.
- Upgrades to the drainage infrastructure.
- Respect the existing valley and minimize environmental impacts of the project (no piers in the valley).
- Safety improvements on both 102 Avenue and Groat Road.
- Accessibility for other modes of transport.
- Wider sidewalks on both sides of the bridge with enhanced barrier protection providing separation between traffic and pedestrians.
- Include bike lanes on the bridge and maintain connectivity with bike routes.
- Vehicle lanes of sufficient width for ETS buses.
- A public art piece created by Alberta artist Faye Heavyshield.
As well, shoring will be installed on the Wellington Bridge just west of the 102 Avenue over Groat Road Bridge in 2014. This work will allow truck traffic to the work site.
The bridge will be closed July 1, 2014, with completion anticipated for fall of 2015.
