Stevenson Dam Bridge

Stevenson Dam Bridge is a concrete viaduct carrying Connecticut Route 34 across the Housatonic River between Monroe and Oxford. The structure consists of multiple concrete arches supporting the roadway above the dam's spillway area.

Construction finished in 1919 when the bridge replaced an earlier wooden crossing downstream. This modern concrete design became the primary river crossing for the region.

The bridge shows how early 1900s engineers connected transportation with water management in a single structure. Visitors can observe this combination while crossing and watching the water flowing beneath.

The bridge carries daily traffic and serves as a direct passage for commuters and local transportation. It becomes busier during rush hours, so plan your visit with typical traffic patterns in mind.

This is the only highway bridge in Connecticut built directly above a dam spillway. The combination of serving traffic while also controlling water flow makes it an unusual engineering solution.
