La Pata Extension Project

Huitt-Zollars prepared the PS&E and right-of-way documents for this 3.7-mile roadway project, which eliminated a gap in the County’s arterial highway system. The highway is a six-lane arterial with a major intersection with SH-74, Ortega Highway. Design challenges for the project included crossing an existing landfill, mountainous terrain, roadway grades up to seven percent, landslide remediation, bridge and tunnel construction, and relocation of an electric transmission tower.
