Overview
- The car left the road between I-95 northbound and Wyman Street in Waltham and ended up in a small retention pond.
- Video from the scene showed the vehicle mostly underwater with only the roof visible.
- MassDOT closed the Wyman Street on-ramp to I-95 northbound to let emergency crews remove the car.
- The closure is expected to last several hours, which could slow access for drivers using that ramp.
- Authorities have not said whether anyone was hurt, and updates are still developing.
