Web Comment: On Wednesday (Oct. 14), the Idaho Transportation Department will begin constructing improvements at the I-84, Exit 26 interchange (to Notus/Parma). Through the end of October, drivers should plan ahead for the I-84 ramps and U.S. 20/26 at the interchange to be closed. The closures will allow crews to repave the on- and off-ramps at Exit 26 and resurface the U.S. 20/26 bridge over I-84. Below is an overview of what to expect from mid- to late October: • The I-84 westbound ramps and U.S. 20/26 (between Old Highway 30 and the I-84 eastbound ramps) will be closed 24/7 for two weeks. • U.S. 20/26 west of the Exit 26 interchange will be intermittently closed for two weeks. • The I-84 eastbound ramps will be intermittently closed for several days. Traffic will be detoured to the interchanges adjacent to Exit 26 (Idaho 44 and Centennial Way). Detour routes will be clearly marked.
