Eastbound I-90 reduced to one lane in Seattle Nov. 13-15: All eastbound lanes will reopen prior to the end of Sunday’s Seahawks game

Washington State Department of Transportation & Sound Transit

Seahawks fans and drivers on eastbound Interstate 90 across Lake Washington will want to plan ahead for another weekend of road work.

Beginning at 11 p.m. Friday, Nov. 13, contractor crews working for the Washington State Department of Transportation and Sound Transit will reduce eastbound I-90 to one lane near Rainier Avenue South. All eastbound traffic will be rerouted to the express lanes during the closure. All lanes will reopen prior to the end of Sunday’s Seahawks game.

Drivers traveling to the eastside of Lake Washington should plan for lengthy delays along Interstate 5, eastbound State Route 520 and eastbound I-90 in downtown Seattle. Those heading to CenturyLink Field or downtown Seattle from the south should consider using alternate routes.

The lane closures on I-90 will provide contractor crews space to upgrade the operations and safety systems in the eastbound Mount Baker and Mercer Island tunnels. The tunnel work is needed before Sound Transit begins work in 2017 to devote the I-90 express lanes to the 14-mile East Link light rail extension.

Keep traffic moving
Thousands of vehicles travel on I-5 through downtown Seattle and across the I-90 floating bridge on a typical weekend. Drivers can help prevent gridlock:
• Know before you go: check the Seattle traffic website, call 511 for real-time travel information, and plan for delays and added travel time.
• Allow extra time to travel through the work zone or on alternate routes.
• Ride transit, carpool or use other alternative modes of transportation.
• Travel early in the morning or later in the evening, or reschedule discretionary trips.
• Those heading to CenturyLink Field or downtown Seattle from the south should consider using alternate routes such as East Marginal Way South, Airport Way South or Fourth Avenue South; or state routes 99, 509 and 599.
• Expect congestion on alternate routes such as I-5, I-405 and SR 520; and on city streets such as Rainier Avenue South, Fourth Avenue South and South Dearborn Street in Seattle.

In preparation for East Link, the now-underway I-90 Two-Way Transit and HOV Operations project preserves the three regular lanes in each direction while adding all-day carpool lanes with direct access ramps for transit, carpools and vanpools.
