Only the northern 1.4 miles (2.3 km) has been built to freeway standards; the rest is a six-lane arterial road.

The route crosses its only numbered interchange at Airport Drive, and then terminates at SR 99.

It was created in 1933 as a western bypass to Bakersfield via Brundage Lane and Oak Street.

LRN 141 started at the intersection of US 99 (Chester Avenue) and Brundage Lane, where it traveled west to Oak Street.

At Oak Street, the route turned north, crossed the Kern River, and terminated at US 99 (Roberts Lane) near Beardsley School in Oildale.

[6] However, that proposal has been dropped in favor of the Westside Parkway connection (known as the Centennial Corridor).

Except where prefixed with a letter, postmiles were measured on the road as it was in 1964, based on the alignment that existed at the time, and do not necessarily reflect current mileage.
