Acceler-8 I-90 Bridge Replacements Project

The Massachusetts Department of Transportation is upgrading eight bridges on the Massachusetts Turnpike (I-90).

The bridges are between Exit 11A (I-495) and Exit 12 (Route 9) on I-90 in the towns of Westborough and Southborough. The bridges, built as part of the original Turnpike, need to be replaced to continue carrying traffic safely and efficiently.
