ID-41: Lancaster to Boekel

An expanded highway will help meet the growing traffic demands on this highly-used corridor between Rathdrum and Post Falls.

One mile of two-lane highway will be expanded to four lanes. It will be divided by either a 50-foot median or a small curb. A path will be constructed to the east of the highway.

Pedestrian improvements

The path will be narrowed from 12 feet to 10 feet north of Nagel Lane, and a parallel path to the west of the highway will be reestablished in this section.

The path will be illuminated at intersections.

Corridor construction

All work to expand ID-41 is planned for completion in 2022. Expansion will start first with the railroad overpass, with most paving done in 2021 and 2022.

The existing highway will essentially become the southbound lanes of the new highway, allowing much of the work to be constructed with minimal impact.

Once work starts, traffic will continue to run on the current lanes while two new lanes and the railroad overpass are built to the east. Once those lanes are finished, traffic will be moved onto that section while the old section is reconstructed.

More details will become available before construction as projects go to bid.


Due to prolonged right of way negotiations, construction of the entire ID-41 corridor has been extended to 2022.
