Boulevard (6200 South). The route slides to the west, entering Taylorsville and crossing 5400 South via overpass with on- and off-ramps (SR-173) and 4700 South. As SR-154 enters West Valley City, it intersects 4100 South, 3500 South (SR-171), and 3100 South. The highway curves northwest, intersecting with Parkway Boulevard (2700 South), Lake Park Boulevard (2400 South), and 2100 South before meeting SR-201 (21st South Freeway) at a diverging diamond interchange and entering Salt Lake City. Losing one lane in each direction, the route meanders northerly toward the Airport, crossing 1820 South and California Avenue (1300 South) before meeting at a cloverleaf interchange at I-80 and terminating at the access road to the Airport. History Planning and construction Planning for the West Valley Highway began in the 1960s as a local federal-aid project. The proposed alignment began at the curve in SR-68 near 15300 South and proceeded north-northwesterly and northerly, following a path much like the present alignment to I-80. It continued north along what was then the west boundary of the then Salt Lake City Municipal Airport No. 1 (now Salt Lake City International Airport) into 4000 West, curving east onto 2200 North and ending at I-215. A drainage canal was moved to make room for a loop from 2200 North onto northbound I-215, but when the Interstate was finished south of 2200 North (where it had ended for many years) in the mid-1980s, a diamond interchange was built instead. Later the north segment was rerouted to continue north-northeasterly from the airport into Davis County; parts of this are now the Legacy Parkway. Salt Lake County was able to build the highway between SR-201 (2100 South) and I-80 with federal funding, but it took the state to finish it. In 1989, the Utah Transportation Commission added a portion of the proposed West Valley Highway to the state highway system as State Route 154. A newly proposed corridor ran west from I-15 near 13400 South to near 3200 West, where it joined the older proposal and headed north to I-80. With the help of Governor Norman H. Bangerter, longtime resident of West Valley City, the project received needed money from the state's general fund, and was opened between SR-201 (2100 South) and SR-171 (3500 South) on November 26, 1991. The Transportation Commission renamed the highway after Bangerter in May 1993. It was finally completed to I-15 on November 17, 1998. Improvements
