The Calvin Coolidge Memorial Bridge is a major crossing of the Connecticut River in Western Massachusetts, connecting the towns of Northampton and Hadley.

The bridge, a replacement of a previous structure destroyed in the 1936 flood,[4] was funded under the Hayden Cartwright Act, one of the numerous federal aid programs designed to provide construction jobs during the Great Depression.

The bridge features large, distinctive granite-faced pylons in the Art Deco style, measuring 15 by 27 feet at the base.

The cobra head luminaires replaced the original low-pressure sodium lamp fixtures developed by General Electric.

The bridge is a major bottleneck in Hampshire County, with the busy Route 9 as the sole thoroughfare between the college towns of Northampton and Amherst.
