Bakersfield is currently serviced by three freeways. State Route 99 bisects Bakersfield from north to south, while State Route 58 exists as a freeway east of SR 99, servicing the southeast part of the city and extending over the Tehachapi mountains to Tehachapi, Mojave, and Barstow. State Route 178 consists of a short segment of freeway that runs from a point near downtown to the northeastern part of the city, although there is currently no direct freeway connection between SR 99 and SR 178.
Bakersfield is the second-largest city in the U.S. (behind Fresno) that is not directly linked to an Interstate highway.
Though interest in extending Interstate 40 to Bakersfield has increased in recent years, lack of funding has prevented the proposed extension of I-40 to a neighboring city, San Luis Obispo.
Currently, plans for freeway alignments to the metropolitan Bakersfield area include three east-west connections on the northern, central, and southern parts of town. These connections would link Highways 58 and 178, the future downtown Centennial Corridor, and the future Kern River Westside Parkway to one another or to State Route 99. In addition, a north-south extension west of Rosedale would connect the southern, central, and northern alignments.
Another plan proposes a link between the northern east-west alignment along 7th Standard Road and Interstate 5. This new connection would be designated Highway 58. Congressional funding has been secured for this 25–35 year project; construction is scheduled to begin by 2010.
Another proposal would upgrade and re-designate State Route 99 as an Interstate highway to be named Interstate 9.
Bakersfield is served by the Golden Empire transit District.
