Public Meeting Notice  Boxborough - I-495/Route 111 Bridge Replacement

What is happening?:

The bridge carrying Route 111 (locally Massachusetts Avenue) over I-495, though safe for all users, has reached the end of its useful lifespan and must be replaced. Replacement of the structure will provide the traveling public with a new bridge with a 75-year design life span built to modern design guidelines for clearance above I-495, shoulders to aid in drainage, and accommodations for non-motorized users.

How will this affect you?:

Construction operations for the bridge replacement will begin in December 2023 with major operations anticipated to run to fall of 2026. Staged construction will be used to keep traffic moving on Route 111. Changes to the intersections abutting the bridge will help avoid congestion and queued traffic on the I-495 mainline. This meeting represents a chance for MassDOT to share construction staging and timing as well as traffic management plans with the Boxborough community. Information about how to receive project updates will also be provided.
