Casco Bay Bridge, Bascule bridge in Portland, US.
The Casco Bay Bridge is a bascule bridge with four traffic lanes that crosses the Fore River between South Portland and Portland. It features dedicated paths for pedestrians and cyclists alongside the roadway.
This structure opened in 1997 following a 1996 tanker collision with the previous bridge that caused an oil spill. It was rebuilt with stricter safety requirements to prevent similar accidents.
The bridge sits at the heart of Portland's harbor life and serves both commuters and maritime traffic daily. For local residents, it represents a practical link that reflects their waterfront identity.
The span opens on demand for passing vessels, with bridge operators communicating with boat captains on VHF Channel 13. Allow extra time during peak hours when vessels may need the bridge to open.
The movable span can open to provide 196 feet (60 meters) of horizontal clearance for passing vessels. This generous opening width allows even large commercial boats to pass without restrictions.
