Interstate 184 (I-184) is a short auxiliary Interstate Highway in Boise, Idaho, United States. The only auxiliary Interstate in Idaho, it is a spur route of I-84 that connects the freeway to Downtown Boise, terminating at US Highway 20 (US 20) and US 26 on the west side of the Boise River.
The western section of the freeway, named the Boise Connector, opened to traffic in December 1968. It was designated as I-180N until a renumbering of I-84 that was approved in 1979. I-184 was extended to a new interchange with US 20 and US 26 in 1992 as part of a new Downtown Boise connector and bridge.
