Work is scheduled to occur during the day and be complete in early August. Crews will be working in the area prior to the closure relocating utilities. Although not expected, night work is allowable.

Project Overview

Construction is ongoing in segments of Chinden between Eagle Road and Star Road. Specifically, paving operations to widen the highway to two-lanes in each direction is underway between Linder Road and State Highway 16, and turning movements are restricted between Locust Grove Road and Eagle as crews prepare this segment for widening. Most work is scheduled for completion in late fall 2020.

The corridor, dubbed ChindenWest, is a vital east-west corridor in the heart of the Treasure Valley. The construction will add travel lanes, widen shoulders, and build a separated path parallel to the roadway.
