T.Y. Lin International Wins 2016 ACEC California Honor Award for I-805 Carroll Canyon Road and High Occupancy Vehicle (HOV) Extension Project in San Diego


T.Y. Lin International (TYLI), a globally recognized full-service infrastructure consulting firm, announces that the I-805 Carroll Canyon Road and High Occupancy Vehicle (HOV) Extension Project in San Diego, California, has won a 2016 Engineering Excellence Honor Award from the American Council of Engineering Companies of California (ACEC California). The project involved the extension of Carroll Canyon Road under Interstate 805, the construction of new HOV lanes in each direction along the interstate highway from I-5 to Carroll Canyon Road, and the construction of a northbound Direct Access Ramp (DAR) from the Carroll Canyon Road Extension to the HOV lanes. As Structures Lead on the Carroll Canyon Road Extension and the construction of the DAR to the HOV lanes, TYLI provided type selection and preparation of Plans, Specifications, and Estimates (PS&E). Structures include a 1600-foot-long viaduct with an elevated intersection, three additional bridges, and six specially designed retaining walls.

The project was developed through a partnership with the California Department of Transportation (Caltrans District 11 and the Office of Bridge Design - South), the Federal Highway Administration (FHWA), the City of San Diego, and the San Diego Association of Governments (SANDAG). Its critical component, I-805, is a vital north-south corridor that passes through the most densely-populated portion of the San Diego region and averages close to 187,000 vehicles each day. One of four projects originally chosen in the San Diego region for Congestion Mitigation and Improvement Account funding through Proposition 1B, the project also received both State and Federal stimulus (ARRA) funding.

“The I-805 Carroll Canyon Road and New HOV Extension Project helps relieve heavy traffic congestion in the heart of San Diego’s busiest employment center,” said Jim Rucker, P.E., TYLI Vice President and Project Manager. “We are extremely pleased that ACEC California has recognized this complex and important project with a prestigious 2016 Engineering Excellence Honor Award."
