Interstate 184, the Boise Connector, travels 3.62 miles from Interstate 84 into the city center of Boise, joining the state capitol with the suburbs. The Boise West Connector opened in December 1968 from Interstate 80N, while I-80N (Boise Bypass) was dedicated in 1969 between Maple Grove Road and Isaacs Canyon.1 The freeway was designated Interstate 180, Interstate 180N, and Business Loop Interstate 84 in its history.
The easternmost extent of the Boise Connector, including the bridge across the Boise River, opened to traffic in August 1992. A two-stage project between February 15, 1999 and September 6, 2004 reconstructed the 1968-built western terminus, "the Flying Wye", from a two-level directional interchange with left-hand ramps into a three-level junction with new flyovers and all movements from the right. The $48.2 million first stage included construction of the three-lane flyover from I-184 west to I-84 east and the expansion of the Boise Connector to six lanes. The second phase of the overall $86 million road work included the addition of separate Franklin Street off-ramps for Interstate 184 east independent of the freeway mainline, eliminating weaving traffic.1,2,3
Speed limits on the Boise Connector were increased from 55 miles per hour to 60 miles per hour on October 30, 2012.4
