Los Angeles Metropolitan Transportation Authority (Metro), I-5 North Managed Lanes PS&E

As a subconsultant to the design team, Guida provided surveying services to support the development of plans, specifications, and estimates (PS&E) for the project. The project was part of Metro’s highway program and begins just north of State Route 14 and extends northerly to just south of Parker Road in Castaic. The improvements included the addition of high occupancy vehicle (HOV)/carpool lanes along the median, addition or improvements to existing truck lanes, and additional auxiliary lanes. These improvements enhanced capacity, operations, and safety by removing trucks from the mixed-flow lanes, enhancing merge-weave areas, and adding a lane dedicated to HOVs.

Guida provided horizontal and vertical control surveys tied to Caltrans District 7 primary controls, coordinated existing survey data, surveyed 9 bridges along the mainline I-5, performed monument perpetuation and preservation, mapping topographic surveys along mainline I-5 and truck lanes, land net mapping, and prepared right of way engineering documents.
