🌉 Highway B-29 Bridge

The Highway B-29 Bridge is a historic bridge in Prairie Grove, Arkansas. It is a single-span concrete arch bridge, carrying Washington County Route 623 across the Illinois River. The arch has a span of 97 feet (30 m), and the total structure length is 100 feet (30 m). Its deck is 17 feet (5.2 m) wide, and the bridge is typically 20 feet (6.1 m) above the water. Built in 1923, the bridge is one of the first built in the county by the Luten Bridge Company, which used an innovative technique involving metal rings that reduced the amount of material required for the structure.
