Mulholland Drive Bridge

Mulholland Drive Bridge. . In 2012 this bridge replaced the historic Mulholland Drive overcrossing that was demolished to accommodate the widening of the San Diego Freeway (I-405). Built in 1959, the original bridge was determined eligible for listing on the National Register of Historic Places in 2004 for its exceptional engineering and construction. Designed by M.A. Shulman with the California Division of Highways, it was an impressive representation of early concrete box girder bridge construction, evidenced in its graceful lines and slim profile. The overcrossing was 579 feet long in three spans, and at the time of construction its 235 foot long central span was the longest of its type in the Western United States. It opened to traffic on April 7, 1960, two years prior to the completion of the freeway. Like the earlier bridge, the new Mulholland Drive overcrossing features three spans of arched concrete box girders, but with a span of 608 feet and a width of 82 feet, the new bridge is both 29 feet longer and 15 feet wider. .
