The Arrawanna Bridge in Middletown, Connecticut, USA, was built in 1918. It brought Berlin Street across the Coginchaug River. The bridge was designed by the Connecticut Highway Department as Bridge No. 4536 and is an open-spandrelconcrete arch bridge. It was listed on the National Register of Historic Places in 2004. The bridge is one of the oldest surviving structures of Connecticut's state highway department, and is the only barrel-arch design of the state's six open-spandrel bridges. "Even as a near ruin, it adds to our appreciation of the high level of technical expertise shown by the state's first bridge engineers, and it recalls the very first years of state-highway bridge construction in Connecticut.":9
At the time it was built, reinforced concrete was a relatively new material for bridge construction. The bridge was featured in the 1918 annual report of the Connecticut Highway Department. The bridge is owned by the city of Middletown.
By 2003, the bridge had been closed for use and was deteriorating in place, with shrubs growing in the roadway.
