Day Long Closures of US 97A to Follow This Week’s Short Delays

The project to remove loose, unstable rock at three locations along US 97A between Entiat and Knapps tunnel begins May 20 and day long closures begin May 26.

These closures are necessary to ensure the safety of the public and crew and expedite the work to reduce overall affects to travel on this section of US 97A.

Closures will occur Monday through Friday from at 8 a.m. to 5 p.m. This closure schedule will be in place May 26 through June 16.

The slopes that have been identified for this work are located at the following locations on US 97A:
-Slope 1: milepost 217.62 to 217.68 between Entiat and the junction of SR 971/Navarre Coulee Road,
-Slope 2: milepost 219.80 to 219.90 between Entiat and the junction of SR 971/Navarre Coulee Road,
-Slope 3: milepost 224.09 to 224.13 between the junction of SR 971/Navarre Coulee Road and Knapps Hill Tunnel.

Lane shifts at Slope 1 and Slope 2 will also be necessary to allow for equipment staging. Lane shifts will remain in place 24 hours a day through the duration of work at those locations. The contractor will install these lane shift on May 20 – May 21, which will require one lane, flagger controlled traffic. Expect up to 20 minute delays during this work.
