Ramp Changes Planned for Needham-Wellesley Section of I-95

MassDOT’s project team will implement ramp changes as part of the Needham-Wellesley I-95 “Add-A-Lane Project.”

The changes at the Route 9/I-95 interchange are scheduled to begin on Friday, September 11, 8 p.m.

New pavement markings, barrier, and temporary traffic control signage to support the new configuration will be in place along with variable message sign boards to alert drivers to the new traffic pattern. The new traffic pattern beginning on September 11 includes the following:

Drivers traveling eastbound (toward Boston) on Route 9 and seeking to access I-95 northbound (toward the Massachusetts Turnpike) will exit Route 9 via a new signalized left-turn lane connecting them to a temporary ramp to I-95 northbound.
Drivers traveling westbound (toward Natick) on Route 9 and seeking to access I-95 southbound (toward Route 1) will exit Route 9 via a new signalized left-turn lane connecting them to a temporary ramp to I-95 southbound.
All other movements associated with the Route 9/I-95 interchange will remain unchanged.

Motorists should note that while the configuration set for implementation on Sept. 11 is temporary, the configuration of left turns described above represents the permanent traffic pattern associated with the I-95 Add-A-Lane project at this location.

As an additional aide to drivers, message boards will be placed on Route 9 alerting motorists to the upcoming change.
