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 carries Route 9 across the river, where it connects to Interstate 91.

History and construction of the bridge

The Calvin Coolidge Memorial Bridge is a five-span, single intersection Warren deck truss bridge with distinctive design on its granite-faced abutment pylons. Art Deco ornamentation on the pylons includes carved eagles and incised carved lettering. 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. It was designed by W & L Engineering Co. in conjunction with Maurice A. Reidy as consultant and Desmond & Lord as architects. The bridge was built by T. Stuart & Sons.

The bridge was named as a memorial to President Calvin Coolidge (1872–1933), a longtime resident and former mayor of Northampton. Coolidge was elected to the State Senate and the governorship of Massachusetts before being elected President of the United States. A bronze memorial plaque of Calvin Coolidge is mounted on the northeast and southwest pylons.

The bridge features large, distinctive granite-faced pylons in the Art Deco style, measuring 15 by 27 feet at the base. On the northwest and southeast pylons are bronze doors that provide access to small rooms.

The 3+12-foot-high (1.1 m) welded steel Art Deco bridge rail is mounted at the back of the sidewalk on the north side of the bridge and on the bridge parapet on the south side where there is no sidewalk. It is a weathered green color. Integral to the rail are light standard posts supporting cobra head luminaires. The cobra head luminaires replaced the original low-pressure sodium lamp fixtures developed by General Electric. These lamps were based on a European model and introduced to the U.S. market in 1933. However, the yellow/orange, monochromatic light produced by the luminaire ultimately became unpopular with the motoring public, and use of the lamps was discontinued as color-corrected light sources became available.

In 2001, the Massachusetts Highway Department began a major improvement of the Coolidge Bridge, that cost a total of $32 million[citation needed] which included:

In 2007 the Massachusetts Historical Commission determined that the Calvin Coolidge Bridge was not eligible for individual listing in the National Register of Historic Places but was eligible for listing as a contributing element in the (then) pending expansion of the Hadley Center Historic District. In 1994, the bridge was included as a contributing element to the Hadley Center Historic District.

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.

The road approaching the bridge is known as Bridge St. in Northampton (eastbound) and Russell St. in Hadley (westbound).
