NORWALK - The driver of a commercial box truck was killed yesterday morning in a crash on the northbound side of Interstate 95 near Exit 16.

The driver, whom state police did not identify, was traveling north at about 6 a.m. in drizzling rain when the truck struck the median and rolled over, ejecting him onto the road, according to a report filed by state police Officer Kenneth Ventresca.

"It's going to be very difficult to get an ID on him," Norwalk Deputy Fire Chief Kenneth Ehlers said.

Cargo from the truck was strewn over I-95 near the crash site, police said. Norwalk firefighters and police helped close the highway, clear debris and gather evidence.

The state medical examiner's office said the cause of the driver's death had not been posted yesterday afternoon.

Portions of I-95 were closed for several hours, including stretches between exits 16 and 17, and near Exit 33 northbound in Stratford, where state police said they located more possible evidence from the accident.

Traffic threaded slowly through Norwalk all morning as vehicles were diverted from the highway.

The white 2006 Nissan truck was registered to Omega Transport Co. Inc. in Pine Brook, N.J.

State police said yesterday afternoon the accident remains under investigation.

- Anyone with information on the accident is asked to contact state police Troop G at 696-2500.
