The Seventh Street Viaduct is 1000 feet (305 meters) long and 56 feet (17 meters) wide. The three reinforced concrete deck arches over the Los Angeles River are 92 feet (28 meters) in length. This viaduct is an interesting and attractive structure in spite or, perhaps due to, the addition of the second deck which was an afterthought rather than part of the initial design. It is unclear from the photograph whether the piers going up to the second deck were added in 1927 or were originally porticoes. Note the nicely detailed lamp posts atop each pier on the top deck. The industrial setting and spray painted art provide an evocative context. It is difficult to imagine how the bridge looked in 1910 when it was originally constructed. The Los Angeles River was not yet a concrete channel. However, it was used as an open quarry for aggregates used in the making of concrete.
