More girders will be lifted into place for Eastside lid construction over 520, meaning it’s time for another weekend closure for the floating bridge across Lake Washington. SR 520 will close from Montlake Blvd in Seattle to I-405 in Bellevue starting at 11pm tonight until noon on Sunday. Drivers will have to divert to I-90 or drive around the lake, but the freeway should reopen to traffic well before the Sounders game on Sunday evening.
Thirty-four girders will be set at the 84th Avenue NE Lid in Medina. From WSDOT:
Each girder is up to 75 feet long and weighs as much as 85,000 pounds. These are the last girders to install on the 84th Avenue Northeast lid before crews can complete the lid deck. Crews still need to place the final girders at the new 92nd Avenue Northeast and Bellevue Way overpasses.
Crews will also shift eastbound traffic to the north at Evergreen Point Road as they make room to build a new median transit stop. Sunday afternoon and Monday morning, drivers should use extra caution adjusting to the new lane alignment.
