Cummings Bridge, Concrete open spandrel deck arch bridge in Ottawa, Canada.

Cummings Bridge is a multi-span open spandrel arch bridge of concrete crossing the Rideau River, linking Rideau Street to Montreal Road between Sandy Hill and Vanier in Ottawa. Built in 1921 and renovated in 1996, it stands about 12 metres downstream from the site of the earlier steel bridge and bypasses Cummings Island.

A wooden bridge was erected in 1835 over the Rideau River, crossing Cummings Island where the Cummings family kept a store. In 1891 a steel bridge replaced it; the city proposed the name Bingham's Bridge after mayor Samuel Bingham, but it did not stick. The current bridge was built in 1921 about 12 metres downstream, bypassing the island.

The bridge construction in 1921 marked a shift in local development, leading to improved connections between Ottawa neighborhoods and the former town of Vanier.

The bridge offers wide sidewalks and clearly marked bicycle lanes making it easy to cross on foot or by bike during daytime hours. Traffic can be heavy during rush periods, so plan accordingly if you prefer a quieter crossing experience.

The 1835 wooden bridge crossed over Cummings Island, where the Cummings family kept a store; the name stuck to both island and crossing. The 1891 steel replacement was meant to be called Bingham's Bridge after mayor Samuel Bingham, but the name never caught on. The 1921 concrete bridge stands about 12 metres downstream and bypasses the island.
