ID-16 to Linder Road

ID-16 to Linder Road improvements are needed to promote safety and increase capacity in this growing region of Idaho.

The widening of this section of Chinden Boulevard from two lanes to four is complete. It will ensure the safety and mobility of the traveling public ahead of new development in the area. The new roadway includes four 12-foot travel lanes, two in each direction, and a detached 10-foot pathway to the south for bicyclists and pedestrians.

Chinden Boulevard, a section of U.S. 20/26, is one of the few east-west commuter routes that connects Boise to Interstate 84 in Caldwell. The majority of Chinden between I-84 and Eagle Road is a two-lane rural highway. As the land around the roadway develops, Chinden is becoming a busy urban corridor, particularly between Ten Mile Road and Eagle.
