Motorists on Columbia Drive and Union Street in Kennewick will encounter construction work through the end of October while crews make road improvements.

Workers will do asphalt grinding, striping, signing and some concrete work and install new asphalt on Columbia Drive from Kent Place to Fruitland Street and on 27th Avenue from Union Street to Highway 395.

Paving is scheduled to occur at night in early October. Motorists can expect delays in the construction areas and are advised to use alternate routes if possible.
