Location

The Arrigoni Bridge, also known locally as the Portland Bridge is a steel through arch bridge carrying Route 66 and Route 17 across the Connecticut River, connecting Middletown, Connecticut, to Portland, Connecticut. When it opened in 1938, the 1,200 feet (370 m) bridge was the most expensive bridge ever built in Connecticut, at a cost of $3.5 million. Its two distinctive 600 feet (180 m) steel arches have the longest span length of any bridge in the state. The bridge has an average daily traffic of 33,600.^[3]

It was named after state legislator Charles J. Arrigoni, who promoted the project. Arrigoni served in the Connecticut House of Representatives from 1933 to 1936 and in the Connecticut State Senate from 1937 to 1940.^[4]
