The Missile Transport Bridge consisted of the design and construction of a 2,098 lineal foot bridge on El Rancho Road over San Antonio Creek. The bridge includes 19 spans with 7-foot dia. CIDH piles of up to 130 ft deep, pile caps, piers, precast girders to support the bridge deck, and 1,329 lf of approach roadway. Related work included new approach pavement, demolition of the existing bridge deck, relocation of existing electrical and communication lines and other utilities, and revegetation and habitat restoration with a one-year habitat monitoring and maintenance period.

The project site runs through an environmentally sensitive wetland with significant endangered species such as the California Red-legged frog, the unarmored three spinned stickleback fish, as well as many archaeological and Native American artifact sites. Environmental permit requirements stipulated construction activity could not take place in the riparian corridor between December 1 and April 15. All construction site personnel were required to receive site-specific training by qualified biologists prior to participating in project activities. Both environmental and cultural resource professionals monitored construction activities.

Quality control was provided by Straub using a blend of the USACE Resident Management System (RMS) for Quality Control adapted to a CalTrans bridge construction methodology. Through careful coordination between the project team, issues were identified early and adjustments made to provide the proper oversight and review, resulting in no quality control issues.
