Spring Maintenance and Inspection Work Planned for US 97-A Knapps Hill Tunnel
The Washington State Department of Transportation has announced maintenance work on the US 97A Knapps Hill tunnel, scheduled for Monday, April 7. This operation will involve flagger-controlled traffic, leading to potential delays throughout the day. Work is set to commence at 7 a. m. and will conclude by 4 p.
m. , with traffic control measures starting around 8 a. m. Drivers on US 97A should anticipate interruptions and may want to consider alternative routes, particularly those traveling between Wenatchee and Chelan, who can use US 97 on the east side of the Columbia River. Additionally, those detouring on Navarre Coulee Rd.
due to the slide on SR 971 South Lakeshore Rd. should allow extra time for their journeys. The maintenance is a necessary step to ensure safety and functionality at the tunnel. For the most accurate travel conditions, it is advisable to check real-time travel maps. Awareness of these delays will help travelers plan their trips more effectively.
