The city will have to repair or replace three of the infamously buckled girders on the 102 Avenue bridge, setting the opening date for the bridge back to summer 2016 at the earliest.

The girders buckled during installation on March 13th. The city's contractor has since been able to straighten them, but found they are still too damaged, at this point, to use as they are.

Groat Road closures between 107th Avenue and River Valley Road 7:30 p.m. Friday May 1st to 6 a.m. Monday May 4th

7:30 p.m. Friday May 8th to 6 a.m. Monday May 11th ​There will be no access to the multi-use path along Groat Road during closures. Parking will be banned along the east side of 116 Street between 100 Avenue and Jasper Avenue for both weekends.

"Now that we're in fact taking four girders down and sending three back to the shop, of course, it's going to take more time," said Byron Nicholson, the city's director of special projects on Thursday.

City crews will close Groat Road for the next two weekends so they can safely remove the damaged girders. After that, they will be returned to the manufacturer where a team of structural engineers will decide if the girders need to be repaired or replaced entirely.

"The city will not accept any loss of integrity of the girders," Nicholson said.

Groat Road will need to be closed again this summer once the girders are ready to be reinstalled.

The city has launched a map on its website that shows all the road closures in Edmonton to help drivers keep track of all the detours.

Once the girders are reinstalled, crews will install the bridge deck and pour the concrete, which may not begin until next construction season.

The 102 Avenue bridge was supposed to open this fall.
