Westside Parkway

Westside Parkway

Traffic Engineering

The proposed Westside Parkway addresses the traffic problems and issues of the metropolitan Bakersfield area. The growing population of west Bakersfield and the lack of east-west arterials in the area make Westside Parkway an important corridor connecting to the Bakersfield Central Business District. Westside Parkway starts as a four-lane divided roadway and expands into an eight-lane divided roadway. The right of way acquired allows it to be expanded ultimately to an eight-lane roadway. As a subconsultant, LIN Consulting is responsible for the design of traffic signals, signal interconnect, and the preparation of transportation management plans (TMP) for various construction segments of the project.
