Via WSDOT:
Montlake Bridge (State Route 513) – Expect delays across the bridge Saturday morning, Nov. 16. Maintenance crews will close the left lane in each direction to vacuum out leaves and trash under the bridge pits where the counterweights sit. The pits need to be cleaned to ensure proper bridge operation as well as prevent debris from piling up and spilling onto the nearby walkways. Some of the work is noisy, and we’ve taken steps to minimize the impact to the neighborhood. Lane closures and preparation will begin at 6 a.m., but the noisiest work will not start until 7 a.m. Everything will be wrapped up by 11:30 a.m.
Roanoke Tunnel – The southbound Interstate 5 off-ramp to State Route 520 will close from 11 p.m. Saturday until 6 a.m. Sunday. During the closure, maintenance crews will service the emergency lighting system inside ramp, also known as the Roanoke Tunnel.
