City of Irvine, Jeffrey Open Space Trail/I-5 Bicycle and Pedestrian Bridge Project

Guida provided land surveying services for the design of a pedestrian bridge over Interstate 5 at Jeffrey Road in the City of Irvine. The bicycle and pedestrian bridge is a cast-in-place (CIP), prestressed (PS) concrete box girder bridge, 1,312 feet long, 6 feet in depth and 17 feet wide, with 9 spans. The bridge spans Walnut Avenue, the Park & Ride lot, the I-5 freeway, the northbound I-5 off-ramp, an existing concrete lined channel, and a maintenance access road. The Jeffrey Open Space Trail and its extensions will ultimately provide a key linkage between trails that extend from the Pacific Ocean to the Santa Ana Mountains and Cleveland National Forest.

Guida worked directly with the design engineering team to provide land surveying, mapping and right of way services—which included horizontal and vertical survey controls tied to Caltrans District 12 primary controls—aerial photogrammetric mapping, supplemental topographic design and utility surveys, land net surveys and mapping, and legal descriptions and plats.
