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. Beginning in the spring of 2024, the Massachusetts Department of Transportation (MassDOT) will fully replace all six bridges. Construction will be staged to reduce impacts on abutters and commuters. The project is expected to run roughly four years.

All detours and lane closures will be noticed using the MassDOT project’s website and mass email system. The project will avoid lane closures and detours during peak commuting hours to help keep traffic flowing.
