Traffic Advisory

Full overnight closures of I-5 in south Seattle Friday, Saturday and Sunday nights

Heads up night owls! Beginning Friday, Sept. 19, to the morning of Monday, Sept. 22, both directions of I-5 between SR 599 and South Boeing Access Road will close nightly so Seattle City Light can install power lines over I-5. During the closures, drivers will follow signed detours. Be sure to plan ahead and give yourself extra time in getting to your destination. For detour information, check out our weekly update of construction closures on I-5 in King County  and scroll down to I-5: Seattle City Light.

WSDOT crews will also perform electronic sign maintenance on the night of Saturday, Sept. 20. This work will reduce northbound I-5 to one right lane between South Boeing Access Road and the I-90 interchange.

SR 99 closures in downtown Seattle rescheduled

We’ve reached that time of year where fickle weather starts playing a bigger role in our construction projects. Due to expected rain tonight, we will not be closing all southbound lanes of SR 99 between S. Atlantic and S. Spokane Streets as originally planned. Full southbound closures are scheduled next week for Monday and Wednesday nights, while full northbound closures are scheduled for Tuesday and Thursday nights. This work is weather dependent and is part of our concrete rehab project. You can also check out our Seattle construction website and look for “SR 99 Pavement Rehab” for more closure information.

Major construction coming to I-5 in Olympia

Drivers are encouraged to avoid Interstate 5 and US 101 in Olympia over the weekend of Sept. 19 while crews replace a bridge expansion joint. Day and night lane and ramp closures could cause lengthy backups and traffic delays. Consider delaying discretionary trips, traveling early or using alternate routes. Amtrak Cascades offers four round trips per day between Seattle and Portland. For specifics on the lane and ramp closures, check the project web page.

Super Bowl rematch this weekend!

 Remember when the Seahawks beat the Denver Broncos in the Super Bowl? What was the score again? Oh yeah, 43-8. Expect similar results and heavy traffic as the teams have a rematch at 1:25 p.m. Sunday, September 21 at CenturyLink Field. While no construction work should slow things down, a sold-out stadium will so be sure to leave early, check our Seattle Traffic page and consider carpooling, public transit or other alternative transportation.

Meanwhile, the 3-0 Washington Huskies meet Georgia State at 3 p.m. Saturday at Husky Stadium. Traffic will be heavy in the Montlake area so again, consider alternative transportation. And watch for SR 520 bridge openings (there’s already one scheduled for 12:30 p.m. that day). We work with boat owners to try to schedule crossings that aren’t too close to game time, but there are no guarantees. Sign up for our free email/text alerts so you know about any 520 openings two hours ahead of time.
