The Arrigoni Bridge, also known locally as the Portland Bridge, is a steel through arch bridge that carries Route 66 and Route 17 across the Connecticut River, connecting Middletown, Connecticut, to Portland, Connecticut. The bridge, which opened in 1938, was the most expensive bridge ever built in Connecticut at the time, costing $3.5 million. Its two distinctive 600 feet steel arches have the longest span length of any bridge in the state. The bridge was named after state legislator Charles J. Arrigoni, who promoted the project. It has an average daily traffic of 33,600. The Arrigoni Bridge was also featured on one of four new U.S. Postal Service stamps in 2023.
