Paving has begun on US 97 in Klickitat County. A single lane in either direction of US 97 between the Biggs Rapids Bridge at mile post 0 and the bridge over the railroad at milepost .5 will close nightly from 9pm to 7am. A single lane in either direction of US 97 between the bridge over the railroad at milepost .5 and Prairie Road at milepost 7.5 may close around the clock. Flaggers and a pilot vehicle will direct traffic through the work zone. Motorists should be extra careful in construction zones. The work is weather dependent. The $2.7 million project is scheduled to be completed in early Fall.
