The cab of a tractor-trailer caught fire on the Southeast Expressway in Dorchester early Thursday, closing all southbound lanes and causing traffic delays in both directions.
The driver was identified by State Police as Mirnes Redzeposki of Utah. No one was injured.
“We got the call at 5:52 a.m., and when we got there, the cab was completely engulfed in flames and the driver was waiting outside,” said Boston Fire Department spokesman Steve MacDonald. “We extinguished the fire and cleared the scene a little before 7 a.m., and State Police are leading the investigation into what caused it.”
“A lot of the evidence was probably burnt up in the fire, but it’s most often mechanical issues that cause these fires,” MacDonald said.
The left lane was reopened on the southbound side shortly before 7 a.m., but traffic remained at a virtual standstill more than an hour later because of “people slowing down to look,” MacDonald said.
Some traffic was diverted onto Morrissey Boulevard to ease congestion.
On the expressway northbound, the high-occupancy lane was closed because of the fire, increasing congestion during the morning commute between Braintree and Dorchester.
