NEWTON, Mass. — Drivers should expect delays now that some ramps on Interstates 90 and 95 are closed for construction of a new Newton-Weston bridge, and the project is expected to last years, state transportation officials said.

On-ramps to I-90 eastbound and westbound from I-95 northbound (Exit 39B), and the I-90 off-ramp to I-95 northbound (Exit 123A) in Newton and Weston are now reduced to one lane in each direction, according to the state Department of Transportation’s website.

The restrictions, which began Sunday night, will continue for the duration of the project, officials said.

“This closure is necessary to help create a safe work zone,” state officials said.

“Drivers traveling through the affected areas should expect delays, reduce speed, and use caution.  Appropriate signage, law enforcement details, and advanced message boards will be in place to guide drivers through the work area,” officials said. All scheduled work is weather dependent and may be impacted due to an emergency.

Work Hours for the project are:

  • Daytime: Monday through Friday from 7 a.m. to 3:30 p.m.
  • Nighttime: Sunday through Thursday from 10 p.m. to 4 a.m. as required
