There are several road and transit closures in the Seattle area this weekend.

Boylston Avenue closures 

The Washington State Department of Transportation (WSDOT) will begin installing a new noise wall at the south end of Seattle’s Ship Canal Bridge this weekend. In early October, WSDOT began clearing trees and preparing the area next to Interstate-5 (I-5) closing the Boylston Avenue East off-ramp. This weekend, WSDOT will once again close the same off-ramp as well as the right lane of I-5 south leading up to the Boylston Avenue East off-ramp, near milepost 168.

The closures are needed to give contractors plenty of space to safely operate a crane used to set the panels, some of which are 36-feet tall. WSDOT is installing this noise wall to reduce the roar from traffic coming from the I-5 express lanes adjacent to the Eastlake neighborhood.

Cliff Mass: Get ready for snow in the PNW this weekend

Work is scheduled to start at 10 p.m, Friday through 5 a.m., Monday and may finish early if the project operates smoothly. For those needing to access Eastlake or head east over the East Roanoake Street overpass at I-5, a detour will first guide drivers to the Mercer Street off-ramp and then north into the Eastlake neighborhood.

Sound Transit 1-Line disruption

This is the 4th weekend out of 6 scheduled weekend disruptions on ST’s 1-Line service in Seattle. During these station closures, ST crews are working on the connectivity to the 2-Line across Lake Washington. This weekend, passengers need to plan around the closures of the University-District, University of Washington, and Capitol Hill stations. ST buses will shuttle passengers between ths stations, running every 10-15 minutes. It is critical for passengers to pay close attention to in-station announcements and destination signs on the tracks to make sure they are boarding the correct train. There will be plenty of ST staff on-hand to answer any questions.

  • U District Station:
    • To Lynnwood: NE 43rd St and Brooklyn Ave NE – Bay 1
