SEATTLE — Drivers should prepare for more highway closures and lane reductions this weekend.
The Washington Department of Transportation (WSDOT) said travelers on Interstate 5 in Seattle and between Federal Way and Tacoma, state Route 99 in Seattle, state Route 520 across Lake Washington, US 2 in Snohomish, and Interstate 405 in Bothell should prepare to encounter delays Friday through Monday.
Most roadwork will happen at night and lane reductions will be in place to help travelers planning trips during daytime hours, according to WSDOT.
I-5 overnight closure
Both directions of I-5 between SR 18 in Federal Way and 54th Avenue East in Fife will close nightly Friday and Saturday to set bridge girders for the SR 167 Completion Project.
Northbound lanes will close by 10:30 p.m. and southbound lanes by 11 p.m. WSDOT said lanes will reopen at 7 a.m. Saturday, with all lanes open by 11 a.m. Lanes will begin to reopen at 8 a.m. Sunday with all lanes open by noon.
Travelers headed to the Fife area should use the signed SR 99 detour route. People with destinations other than Fife should consider using regional routes such as SR 18, SR 161, SR 167 and SR 512.
I-5 southbound overnight lane reductions
According to WSDOT, southbound I-5 in Seattle from mid-Boeing Field to Interurban will have three of five lanes closed for restriping as part of the state's efforts to maintain the aging highway.
Lanes will close at 9 p.m. Saturday and reopen at about 7 a.m. Sunday. WSDOT said lanes will begin closing at 9 p.m. Sunday and reopen by 5 a.m. Monday. Multiple ramps will be closed at the same time.
This roadwork may be canceled and rescheduled in the event of rain, WSDOT said.
SR 99 closure
The SR 99 tunnel in Seattle will close from 10 p.m. Friday through 6 a.m. Sunday as crews start the first federally mandated six-year inspection. During this time SR 99 will be closed southbound at Harrison Street and northbound at the Alaskan Way off-ramp.
SR 520 closure
Travelers should plan on SR 520 closing from 11 p.m. Friday through 5 a.m. Monday between I-5 in Seattle and 92nd Avenue Northeast in Clyde Hill on the Eastside, including all associated on-and off-ramps.
During this closure, officials said the SR 520 Trail will also be closed to bicyclists and pedestrians. WSDOT crews will be testing the light and fire suppression system under the Montlake lid over SR 520 as part of the SR 520 Montlake Project.
US 2 closure
Both directions of US 2 will close between SR 9 and 88th Street Southeast in Snohomish from 10:30 p.m. Friday to 2 a.m. Saturday. There will be signed detours via SR 9 and Second Street. WSDOT maintenance crews will perform survey work, sweep the highway, and clean roadway and bridge drains in preparation for the rainy and colder months ahead.
I-405 southbound overnight lane reductions
There could be up to three lanes of southbound I-405 between SR 522 and Northeast 160th Street near Bothell closed from 11 p.m. Friday to 11 a.m. Saturday, while crews shift traffic for the I-405/Brickyard to SR 527 Improvement Project.
According to WSDOT, multiple ramps will be closed from 2 to 11 a.m. Saturday. This work requires dry weather and could be rescheduled.
Ballard Bridge in Seattle
Due to maintenance, the 107-year-old Ballard Bridge will be closed from Friday night through Monday morning.
