The City of Lewiston has announced that nighttime construction will begin on Monday, April 20 along Snake River Avenue as part of a major roadway improvement project. Crews will work overnight between 8 p.m. and 6 a.m., with drivers expected to encounter periodic lane closures, flagging operations, and shifting traffic patterns. The project, which has been in development since 2014, is scheduled to run from April through October 2026 and will include reconstruction of the roadway, installation of a stormwater drainage system, and the eventual widening of Snake River Avenue to three lanes.

Why it matters

This project is a significant infrastructure upgrade for Lewiston, addressing long-standing issues with the Snake River Avenue corridor. The improvements will enhance traffic flow, pedestrian safety, and overall accessibility in the area, which is important for both residents and businesses.

The details

The initial work will begin near the Southway Avenue roundabout and move north toward 11th Avenue, including improvements along 11th Avenue. Planned upgrades include reconstruction of the roadway, installation of a stormwater drainage system, and the eventual widening of Snake River Avenue to three lanes — one in each direction with a shared center turn lane. Additional improvements will include curb, gutter and sidewalk installation, ADA-compliant pedestrian ramps, and other infrastructure enhancements. Final paving, striping, and signage are expected to be completed later in 2026.
