The Colorado Street Bridge was designed and built in 1913 by the Kansas City (MO)-based firm of J.A.L. Waddell. With a span of 1,486 feet and known for its distinctive Beaux Arts arches, lights, and railings, the bridge is on the National Register of Historic Places and has been designated a National Historic Civil Engineering Landmark by the American Society of Civil Engineers. In 1989, after the Loma Prieta earthquake in Northern California, the bridge was declared a seismic hazard and closed to traffic. It was reopened in 1993 after a substantial retrofit.
