Temporary closures required for Eastside upgrades, work on new bridge
SEATTLE – A series of temporary lane and ramp closures on State Route 520 are slated in coming weeks as part of the Washington State Department of Transportation’s ongoing work to build a stronger, safer highway corridor across Lake Washington.
The closures, beginning tonight, will allow WSDOT contractors for the SR 520 Bridge Replacement and HOV Program to perform a variety of important construction activities.
“Most of our construction work can be done without interfering with traffic, but certain projects simply demand closing off highway lanes or access ramps to ensure the safety of workers and motorists alike,” said Julie Meredith, WSDOT’s SR 520 program director. “We try to limit the number and duration of these closures as much as possible.”
A map of the closure locations is posted on WSDOT’s SR 520 website. Below is a breakdown of the planned traffic restrictions on SR 520 in coming weeks:
March 6 and 10: 84th Avenue Northeast westbound on-ramp
- Both lanes of the on-ramp will close from 9 p.m. to 5 a.m. Thursday and Monday; outside of these nighttime closures, the ramp’s right lane will remain open to all traffic.
- Construction: Finish on-ramp paving; construct the foundation for a sign bridge spanning the highway; install traffic barriers.
March 7-10: 108th Avenue Northeast/Northup Way intersection and westbound ramps
- The intersection and nearby highway ramps onto and off SR 520 will close at 10 p.m. Friday and reopen by 5 a.m. Monday.
- Construction: Finish installation of underground drainage and utility lines; install permanent traffic barrier along the westbound on-ramp.
March 12, 13, 20, 27: SR 520 westbound lanes
- Both westbound lanes between Montlake Boulevard and 92nd Avenue Northeast will close from 11 p.m. to 5 a.m.
- Construction: Build piers on Lake Washington for the new West Connection Bridge, just north of the existing SR 520 floating bridge; set concrete noise-wall panels between 92nd Avenue Northeast and 84th Avenue Northeast.
March 21-24: 84th Avenue Northeast eastbound off-ramp
- The ramp will close from 11 p.m. Friday, March 21 to 5 a.m. Monday, March 24.
- Construction: Realign off-ramp to facilitate noise-wall construction and utility installation work.
March 28-31: 92nd Avenue Northeast eastbound on-ramp
- The on-ramp will close from 11 p.m. Friday, March 28 to 5 a.m. Monday, March 31.
- Construction: Continue building the permanent on-ramp and permanent traffic barrier along the ramp’s north edge.
March 29: Overnight closure of Eastbound SR 520
- All SR 520 eastbound lanes between Montlake Boulevard and I-405 will close from 11 p.m. Saturday, March 29 to 6 a.m. Sunday, March 30.
- Construction: Realign the highway’s eastbound lanes near 92nd Avenue Northeast to create a work zone for wall construction.
Throughout March: SR 520 floating bridge
- One westbound lane on the floating bridge will close intermittently throughout March; these overnight closures are from 9 p.m. to 6 a.m. See SR 520’s Orange Page for specific dates.
- One eastbound lane near the floating bridge’s west approach will close intermittently throughout March; these overnight closures are from 9 p.m. to 6 a.m. See SR 520’s Orange Page for specific dates.
- Construction: Perform utility relocations and other pier-building activities for the new West Connection Bridge, which will link the new SR 520 floating bridge with the highway’s existing four-lane section in Seattle.
Highway construction is subject to weather and other factors, and scheduling can change. The SR 520 Orange Page provides up-to-date information on closures and key construction activity.
When completed, the SR 520 program will replace the existing Evergreen Point Floating Bridge on Lake Washington with a safer structure, dedicated lanes in each direction for buses and high-occupancy vehicles, a separate path along the highway corridor for bicyclists and pedestrians, and environmental improvements along SR 520 between I-5 in Seattle and SR 202 in Redmond. The Eastside Transit and HOV Project is scheduled to be completed later this summer. The new floating bridge is expected to open to traffic in early 2016.
