Antonio Parkway and Bridge Widening

GMU has worked with Rancho Mission Viejo and the County of Orange to provide geotechnical design and construction services for the road and bridge widening on Antonio Parkway and a portion of La Pata Avenue. The project includes widening this County arterial highway from 4 lanes to 6 lanes, plus widening of the existing 780-foot long, 5-span bridge over San Juan Creek. For the bridge widening, GMU’s Foundation Report included detailed analysis and recommendations for liquefiable soils that influenced bridge foundations.
