Drivers should plan ahead for more construction congestion July 8-11 when SR 520 again closes from Montlake Boulevard in Seattle to I-405 in Bellevue. At the same time, city of Seattle crews are closing the I-5 ramps to and from Mercer Street for construction.
All highway ramps and mainline lanes in the work zone will close at 11 p.m. Friday, July 8. SR 520 will remain open between I-5 and Montlake Boulevard, and east of I-405.
Nearly 166,000 cars and buses cross SR 520 on a typical summer weekend, and we need people to shift how and where they travel. Between SR 520 and the I-5 ramp closures, congestion is expected to increase on I-90, I-5 and I-405, especially from 10 a.m. to 8 p.m. Saturday, July 9.
By closing the highway for construction on the weekend, we can keep traffic flowing during weekday commutes. On SR 520, construction crews plan culvert installation to improve fish migration as part of the Eastside Transit and HOV Project. At the same time, maintenance crews will spend the weekend testing, inspecting and repairing components of the floating bridge to prepare it for the next storm season.
The highway and ramps will reopen by 5 a.m. Monday, July 11. Details about the major weekend closure are posted online, and other lane and ramp closures are updated regularly on our construction information page.
Major work accomplished during the June bridge closure
Crews worked hard June 17-20 on a big list of construction activities on SR 520 between Medina and Bellevue, including demolishing a pedestrian bridge, installing a massive concrete culvert and building a new eastbound off-ramp to Bellevue Way Northeast. Some of our favorite pictures are posted online – nearly 1,900 people have already taken a look at these amazing shots!
Drivers helped reduce the potential congestion by changing how and where they traveled. We'll need help from drivers again July 8-11, and during future weekend closures expected each month during construction season.
