Overview
- Crews found a tractor‑trailer fully engulfed around 8:30 p.m. Tuesday night at about Mile Marker 90–90.5 on the eastbound Massachusetts Turnpike.
- All three eastbound lanes were closed and traffic was diverted off Exit 90 while firefighters extinguished the blaze and crews worked the scene.
- The Auburn Fire Department estimated roughly 100 gallons of diesel leaked onto the roadway over about 100 yards, prompting notification of the Massachusetts Department of Environmental Protection and the Auburn Water Department.
- Officials have not confirmed any injuries and say the cause of the fire remains under active investigation.
- The shutdown caused local traffic delays on a major east–west corridor and officials said motorists should use alternate routes while cleanup and water‑quality monitoring continue and further updates are expected.
