Southbound traffic on Interstate 95 was delayed for about four hours Wednesday afternoon and evening after a tractor trailer overturned across the roadway just north of the Fort McHenry Tunnel.
Officials with the Maryland Transportation Authority said the truck was carrying heavy stone slabs that were thrown all across the highway during the accident.
"It's not as easy as just getting a sweeper out there, because they are very, very heavy pieces," said Cheryl Sparks, a MdTA spokeswoman.
Sparks said there are also "a lot of little pieces broken up everywhere."
All lanes were initially closed. About two hours after the crash, two right lanes of traffic were getting by at the scene, and by 7:30 p.m. all llanes of traffic reopened.
The accident occurred south of Eastern Avenue about 3:19 p.m., and only involved the tractor trailer, Sparks said. There were no reported injuries.
Southbound traffic on the highway was being pushed to the far right of the highway, initially squeezing by on a shoulder, the MdTA said. Drivers were advised to take Interstates 895 and 695 as alternates.
Sparks said she did not have a cause for the accident.
