WSDOT Issues Roadwork Alerts for I-90, I-405 and SR 520

Overnight roadwork on area highways meant to manage congestion are scheduled to take place over the next several weeks.

On Interstate 90, crews closed both directions of the mainline lanes and floating bridges and will do so again tonight. Traffic from all eastbound lanes from the Mt. Baker Tunnel across the floating bridge to Mercer Island will be diverted into the I-90 express lanes until 4 a.m. Wednesday. Westbound lanes from 150th Avenue in Bellevue to Seattle will be reduced one lane at a time, from 7 - 11 p.m. The lanes will re-open at 5 a.m. Wednesday. The work is part of a muti-year Active Traffic Management project that began in 2007.

The closures come at a time work is also taking place on the I-90 express lanes, which are temporarily reduced between 80th Ave. SE and Shorewood Drive.

Meanwhile, the State Route 520 floating bridge will be closed overnight Tuesday evening through Thursday morning as state transportation crews test new tolling equipment.

According to the Washington Department of Transportation (WSDOT), a gradual closure will begin at 11:30 p.m. Tuesday, when crews shut down one lane of westbound traffic between 92nd Avenue Northeast and Montlake Boulevard.

The second lane will close at 11:59 p.m. One lane will reopen at 4:30 a.m., and both lanes will be open by 5 a.m.

The same closures will affect eastbound traffic from 11:30 p.m. Wednesday through 5 a.m. Thursday.

And later this month, WSDOT crews are readying a major closure of Interstate 405 through downtown Bellevue, April 1-4. Crews will close I-405 in both directions between NE Eighth Street and SR 520 from Friday, April 1 at 11 p.m. to Monday, April 4 at 4 a.m. Planners are calling the I-405 closure "the biggest this construction season."
