New SR 520 westbound lanes now open

Important! Westbound: Straight AheadThe new West Approach Bridge North’s three westbound lanes on SR 520 opened to traffic on Monday, Aug. 28. Westbound motorists now drive straight ahead while crossing Lake Washington rather than curving left from the new floating bridge onto the old west approach structure. Watch this video to see how the new approach bridge changes cross-lake travel. 

SR 520's shared-use path to cross lake, reach Seattle this fall


You don't have to wait much longer. The new bicycle and pedestrian path along SR 520 is scheduled to extend from the floating bridge to Montlake this fall. It's going to be a great ride ... or run ... or walk! 

Meet our new SR 520 ombudsman
We have a new ombudsman for the SR 520 Program. His job is to look into community concerns or suggestions about our construction work and its effects on neighborhoods in the corridor. Watch this video to hear our ombudsman, David Goldberg, discuss his new role.

Program Overview

The SR 520 Bridge Replacement and HOV Program is enhancing public safety and mobility by replacing the highway's aging, vulnerable bridges and making significant transit and roadway improvements throughout the corridor. The construction program's planned improvements extend from I-5 in Seattle to I-405 in Bellevue.
