ID-41: Prairie to Lancaster

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

Three miles of two-lane highway will be expanded to four lanes divided by a 50-foot median. A structure over the railroad between Hayden and Wyoming avenues will be added, and signals will be installed at Lancaster Road and Nagel Lane. A path will be constructed to the east of the highway.

Construction in 2020-21

Railroad overpass

An overpass will be constructed over the railroad tracks between Hayden and Wyoming avenues. Twin bridges each approximately 140 feet long and 55 feet wide will provide 24 feet of clearance over the tracks.

The 12-foot path will continue on both sides of the overpass to provide for future and existing connections. The path on the north side will have illumination, but both will be separated from traffic by concrete barrier.

Intersection changes

Two signals will be installed at Lancaster Road and Nagel Lane. The intersection with Lancaster Road will have dedicated turn lanes in all directions, but the Nagel Lane intersection will not have a dedicated right turn lane.

The signal at Hayden Avenue will be replaced, and components of the Boekel Avenue signal will be upgraded.

Intersections will be illuminated.

Construction

Improvements from Mullan Avenue in Post Falls to Boekel Avenue in Rathdrum are scheduled to be constructed in 2020 and 2021. 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.
