The widening project on State Route 410 in Bonney Lake means motorists can expect nighttime closures and short delays this week.
Construction crews are working from 6:30 a.m. to 4:30 p.m. between 214th and 234th avenues and trucks will be coming in and out of the work zone.
At night, flaggers will control one-way, alternating traffic from 8 p.m. to 4 a.m. until Friday. They will also be working from 8 p.m. Saturday until 8 a.m. Sunday.
Traffic is scheduled to shift from the south side of the highway to the north side so they can widen that section of roadway, which means 233rd Avenue will be closed where it intersects with SR 410.
That closure will last from 7 a.m. Tuesday until 8 a.m. Sunday. A signed detour will be posted.
The traffic shift will begin at 8 p.m. Saturday and the roadway reopens in its new temporary alignment by 8 a.m. Sunday, according to the state Department of Transportation.
Nickel and Transportation Partnership are funding the $29.3 million project, which will add one lane in each direction on SR 410 and include a raised median separating the east and westbound traffic.
A new traffic signal at the intersection of 233rd Avenue East and 234th Avenue East is expected to reduce collisions and improve mobility.
The project also includes bus stop improvements, lighting at the traffic signals and stormwater treatment facilities.
