Construction of the Broadway–Chinden Connector, which would connect I-184 with downtown Boise, began in January 1988 and cost $60 million to complete. The new bridge across the Boise River was opened on August 7, 1992, replacing a pair of smaller bridges to the north. The westernmost segment of I-184, including the Flying Wye interchange, was rebuilt from 1999 to 2004 to accommodate an additional set of lanes. The project cost $86 million (equivalent to $ in ) and was delayed approximately six months due to financial constraints and delays in bridge construction in the initial phase of the project.
