A contractor doing the finishing touches on the widening of Interstate 90 east of Sullivan Road is going to force lane restrictions through the work zone today through Monday.
The work could cause congestion and delays, according to the Washington Department of Transportation.
The restrictions are needed to allow a realignment of lanes onto their permanent configurations.
As drivers know, the stretch from Sullivan to Barker roads is being improved from two to three lanes in each direction.
Eastbound traffic will be reduced to a single lane at 9 a.m. today through 3 p.m. and again from 7 p.m. to 6 a.m. on Friday.
The eastbound restrictions will continue on Friday during the same hours. Two-lane traffic is expected on Monday.
Westbound traffic will have two lanes through the weekend.
On Monday, westbound traffic will be reduced to one lane from 7 p.m. until 6 a.m. The contractor will remove temporary concrete barriers to open traffic to three lanes.
