New Bay Diner Restaurant
Also known as: Route 66 Diner; Mountain View Diner #532
Why it's listed
This stainless steel diner at 950 Bay Street in Springfield was built in 1957 by Mountain View Diners of Signac, New Jersey, and shipped to the site that year. It is seven bays wide, with red horizontal bands, a rounded hipped roof, and a rear concrete block annex housing the kitchen. Inside, it keeps its manufacturer's tag, a full-length counter with seventeen stools, six booths, stainless steel finishes, and terrazzo flooring. It was listed because it is the last diner in Springfield and one of about six surviving Mountain View diners in Massachusetts. It is believed to be the second-to-last diner the company produced before closing in 1957. By 1964 it was known as the New Bay Diner Restaurant, a name reflecting a trend toward family dining with booth service to compete with fast food chains. Its current name refers to historic US Route 66. The diner remains a working restaurant and retains its original design and materials.
Significance in brief: The diner is the last remaining diner in Springfield and one of only about six Mountain View diners left in Massachusetts. It is believed to be the second-to-last diner built by Mountain View before the company closed in 1957. It retains integrity and is considered significant at the state and local levels for architecture and commerce.
