Project Area

The work on I-95 begins approximately 1,000 feet north of the Needham Branch RR Bridge in Needham and continues to 5,000 feet north of Route 9 in Wellesley, approximately 3.8 miles.

Project Overview

This project is the sixth and final contract to provide an additional travel lane and shoulder toward the median on I-95 from approximately Route 24 in Randolph to Route 9 in Wellesley. This widening includes restoring the breakdown lanes for their intended use. This sixth contract is a 3.8-mile segment of I-95 from just north of the Needham Branch railroad bridge in Needham to about 5,000 feet north of Route 9 in Wellesley.
