Excellence Award Winners

Cotter Bridge, AR

Cotter Bridge, Arkansas State Highway and Transportation Department (AHTD)

Completed in 1930, the Cotter Bridge on U.S. Highway 62B over the White River is an excellent example of the Marsh Rainbow Arch construction technique. After 70 years of continuous use, however, the bridge needed major repairs. Through such measures as requiring that concrete work replicate the original design of the bridge, AHTD was able to preserve the historic integrity of the structure while improving safety.

Merit Award Winners

Laurel Street Bridge Emergency Repair Project, Caltrans and the City of San Diego, California

Listed as a National Historic Landmark, the Laurel Street Bridge in Balboa Park was built for the 1915 Panama-California Exposition. After Caltrans determined that spalling concrete and other deterioration necessitated repairs, a consulting historical architect with experience in concrete restoration work was hired to provide guidance throughout the project. The restoration of the bridge ultimately improved safety while retaining the historic appearance of the structure. Contact: Bruce Lambert, Caltrans, 619-688-3313 (email: bruce.lambert@dot.ca.gov).
