Drivers should plan ahead this weekend, April 27-30, when traffic crews will close the SR 520 bridge to install girders on the Eastside. Beginning 11 p.m. Friday, April 27, crews will close all lanes between Montlake Boulevard in Seattle and I-405 in Bellevue. During the closure, crews will set 42 massive concrete girders at 84th Avenue Northeast to support a new lidded overpass and interchange. All lanes will reopen by 5 a.m. Monday, April 30.
On Monday, changes along the highway work zone will require buses to merge with general traffic west of 92nd Avenue Northeast. This lane shift allows westbound traffic a longer merge with improved visibility from the 84th Avenue Northeast on-ramp.
