Idaho State Highway 67


State Highway 67 is a state highway in Elmore County, Idaho. It connects the Mountain Home Air Force Base to SH-51 in the city of Mountain Home.

Route description

SH-67 begins at the main entrance of the Mountain Home Air Force Base, located in southwestern Elmore County. The five-lane highway, named Airbase Road, travels due north from the base entrance to a junction with Grand View Road. From the junction, SH-67 turns northeast and travels through a section of the Morley Nelson Snake River Birds of Prey National Conservation Area in the barren outskirts of Mountain Home as a four-lane, undivided highway. The highway then enters the city of Mountain Home and turns east before passing a municipal airport. SH-67 terminates at an intersection with SH-51 near the east end of the airport, located approximately west of an interchange with Interstate 84. Except for a brief divided section at the intersection with SH-167, the entire highway is four-lane non-divided, with center lane-left turn only areas where needed.

History

The history of SH-67 goes back to at least the 1930s, when the first all-weather gravel road connecting Grand View and Mountain Home was built, and can be seen on a 1937 map of the area. A road from this road to the site of the base has existed since at least November 1942, when base construction began.
The route received its current number designation in the late 1960s in honor of the base's then-host unit, the 67th Tactical Reconnaissance Wing.
The original SH-67 also included the entirety of SH-167 from Grand View to where it currently intersects with SH-67 approximately from the base's main gate.
In order to improve the base's prospects to remain open during a round of base closures in the 1970s, Idaho's legislature voted to expand the highway to the base to four lanes, although it was an area noted for gusty winds and tumbling tumbleweeds and little else. The expansion project also realigned the highway to go directly to the base's main gate. The unexpanded two-lane section of SH-67 that passed to the west of the base was delisted and unsigned prior to its redesignation as SH-167.
