Great Bridge at McConkey's Ferry
The Great Bridge over the Charles River connected Cambridge, Massachusetts to Little Cambridge, which was the name for Allston-Brighton before it separated from Cambridge in 1807, first becoming the town of Brighton and finally joining the city of Boston in 1874. The Great Bridge was built in 1660-1662 at what was then called Brighton Street, and was the first bridge to span the Charles. A toll was authorized in 1670, rebuilt in 1862.
