Geocon worked with the design-build team of Skanska/AECOM to design the 3½-mile High Occupancy Vehicle/Bus Rapid Transit (HOV/BRT) lanes on Interstate 805 from State Route 52 North to Mira Mesa Boulevard in San Diego. The total project cost is estimated to be $175 million with the current geotechnical work exceeding $550,000. Five major structures will be required including four bridge widenings and tieback retaining walls up to approximately 50 feet in height for the Direct Access Ramp. Other improvements include new roadway pavements, retaining walls, infiltration basins, and numerous post sign structures.
