- Wednesday, Feb. 4: The southbound SR 99 off-ramp to South Royal Brougham Way (milepost 30) will close for maintenance work.
- Thursday, Feb. 5: The left lane in both directions of SR 99 will close at Alaskan Way/Dearborn Street (milepost 30) for maintenance work.
Friday at 10 p.m., both directions of the downtown tunnel will close for regular maintenance operations. Lanes will begin closing at 8:30 p.m. with all lanes reopening by 6 a.m., Saturday, Feb. 7.
During this closure, southbound drivers on State Route 99 (SR 99) will have to exit at Harrison Street, while northbound drivers on SR 99 will have to exit at Alaskan Way. The 6th Avenue and Royal Brougham on ramps will also be closed during maintenance hours.
