I-495 Andover-Lawrence Bridge Replacements

The I-495 Andover-Lawrence Bridge Replacements Project includes six bridges on I-495. The structures are on I-495 where it follows the Andover-Lawrence border. 

I-495 is a vital connector linking eastern Massachusetts to Cape Cod and southern New Hampshire. Private vehicles and heavy trucks delivering freight across the Commonwealth travel this interstate. Route 28 is a regional road that connects homes, businesses, medical care, and educational opportunities. Within the project area, on average, I-495 north and southbound each carry 57,000 vehicles each per day. Route 28, north and southbound each carry an average of 14,700 vehicles per day.

Beginning in the spring of 2024, MassDOT will fully replace all six bridges. This project allows MassDOT to provide the following improvements to all users:

• New bridges with fewer supports and expansion joints; meaning less impacts to roadway users from maintenance activities.
• Wider bridges that meet modern safety standards with more space on their decks will help to accommodate future maintenance activities.
• Safer acceleration and deceleration lanes for traffic entering and exiting I-495.
• Wider sidewalks and new bicycle lanes on Route 28.
