Highway 224 in West Richland will be reduced to one lane between Highway 240 and Bombing Range Road from 8 p.m. to 5 a.m. Tuesday through Thursday for construction.
Some lanes will be closed so crews can stripe the roadway and install guide posts. One lane will remain open in each direction.

This work is part of a project to replace asphalt on Highway 224 from Bombing Range Road to Highway 240 and on Highway 240 from Hagen and Robertson roads to Swift Boulevard.
Highway 395 also will be closed in both directions at the Court Street interchange in Pasco from Tuesday through Friday as crews replace a girder that was damaged when construction equipment on a semi-truck crashed into the bridge's support girders.
Traffic will be detoured on the off ramp and back down the on ramp at the Court Street interchange.
Southbound trucks will be prohibited during the closure, because the state Department of Transportation says the construction zone will be tight. The state suggests trucks use Interstate 182 west to Highway 240 for local delivery or I-182 west to Interstate 82 east for through traffic.
The Washington State Patrol will assist with traffic control and will enforce the closure.
Court Street will be reduced to one lane in each direction on the bridge and near the Highway 395 interchange area while the girder is replaced and other girders are repaired.
The project is expected to finish in early November.
