Avista, the utility company, plans to close a portion of roadway near the intersection of First Street and Main Street in Lewiston, Idaho overnight on February 19-20 to complete scheduled infrastructure work. The closure will affect westbound traffic traveling from Lewiston to Clarkston across the Interstate-Blue Bridge, with drivers being rerouted south on Snake River Avenue and across the Southway Bridge. The overnight work includes replacing power poles along First Avenue and Main Street, and a small number of customers may experience a brief, planned power outage during construction.

Why it matters

The overnight road closure will disrupt traffic patterns in the Lewiston area, potentially causing delays and inconvenience for drivers. However, the work is necessary for Avista to upgrade equipment and maintain reliable electrical service in the region.

The details

The road closure is scheduled to begin at 6 p.m. on Thursday, February 19, and is expected to be completed by approximately 4 a.m. on Friday, February 20. During this time, westbound traffic traveling from Lewiston to Clarkston across the Interstate-Blue Bridge will be closed and rerouted. Drivers heading westbound will be directed south on Snake River Avenue and routed across the Southway Bridge. Traffic traveling from Clarkston to Lewiston via the Interstate-Blue Bridge will not be affected.
