Ouachita River Bridge (Arkadelphia, Arkansas)

The Ouachita River Bridge is a steel Parker through truss bridge carrying Arkansas Highway 7 and Arkansas Highway 51 across the Ouachita River at Arkadelphia, Arkansas. The trusses of the bridge were manufactured in 1933 by the Luten Bridge Company, and were first used to carry Highways 7 and US 67 over the Caddo River. That bridge was disassembled in the 1950s, and the trusses were stored until used to build this bridge in 1960. The main trusses span 202 feet (62 m), while the approaches combined measure 301 feet (92 m), giving the bridge a total length of 503 feet (153 m). The deck is concrete laid on steel girders and is 24 feet (7.3 m) wide. It is one of two crossings of the Ouachita River in Clark County.[2]
