The West Bakersfield Interchange is a freeway interchange in Bakersfield, California, west of downtown. It connects State Route 99 (Golden State Freeway) with SR 58 (Mojave Freeway). These routes represent the heart of the Bakersfield freeway network. They connect the city with commercial centers in the San Joaquin Valley, ports in Los Angeles, and major Interstate freeways serving southern and eastern America. The original interchange plan was more elaborate. Five freeway segments (three signed routes) would connect through a series of three interchanges, forming a triangle. Those routes were SR 99 (Golden State Freeway), SR 58 (Mojave Freeway/Westside Parkway), and SR 178 (Crosstown Freeway). However, only three segments and part of one interchange were constructed. Currently, SR 178 terminates about east of the interchange. In addition, the eastern terminus of the Westside Parkway is about west of the interchange. Since the interchange is being designed relatively late, compared to other major California freeway interchanges, several design elements are incorporated to help alleviate traffic. Unlike the East Los Angeles and Orange Crush interchanges, the three Kern County interchanges will be widely spaced (between ) from one another. Also, local interchanges within of it will transition onto their own parallel roads, and merge with the mainline after the main interchange. ==History== Construction on the north–south Golden State Freeway (SR 99) was completed in the early 1960s. Between 1974 and 1976, the Mojave Freeway (SR 58) was extended to the Golden State Freeway from the east. The first of the interchanges was partially constructed with a stub for the future western extension, which would also become the southern leg. The western extension as well as the northern leg of the interchange were not constructed. It was delayed first by a four-year freeway construction moratorium imposed by Governor Jerry Brown (1977–81) and was followed by 25 years of opposition from the City of Bakersfield (1980–2005). During that same time period, Bakersfield saw large growth in both population and economic development. The existing interchanges, including the partially constructed freeway-to-freeway interchange, began seeing severe traffic congestion. Both cars and trucks were using the existing infrastructure to transition to and from both the existing freeways, as well as Rosedale Highway/24th Street (SR 58/SR 178), which are local arterials used to connect to other freeways. By the early 2000s, traffic was becoming a large enough problem that improvements needed to be completed. Federal money was secured for the construction of the southern leg of the interchange, which connects the Mojave Freeway to the Westside Parkway. This will also complete construction of the existing interchange, and provide improvements which will be incorporated into the future construction of the other two interchanges. The city would also drop its opposition to the project, with the city council voting to give Caltrans full control over it.〔 They city would retain control over the construction of the Westside Parkway. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「West Bakersfield Interchange」の詳細全文を読む スポンサード リンク
