A tractor trailer hauling 12 shipping tons of a petroleum-based liquid overturned Monday morning on Interstate 95, closing the northbound lanes for hours just south of downtown Baltimore while crews cleaned the product spilled over the road.
The tractor trailer overturned shortly before 11:30 a.m. on northbound I-95 past Exit 52 for Russell Street, firefighters said. Northbound lanes were closed until about 4 p.m., but reopened in time for crowds coming into Baltimore for the Orioles and Nationals baseball game. Orioles officials were monitoring the cleanup.
Most days, 174,200 vehicles travel northbound and southbound past the crash site, according to state highway officials. The wreck halted northbound traffic for about four hours.
The tractor trailer was hauling Polyether modified trisiloxane, a product sometimes used in agriculture and mixed with pesticides. The product helps pesticides stick to plants.
Initially, firefighters said two state employees were injured from exposure to the spilled product. But 1st Sgt. Jonathan Green, spokesman for the Maryland Transportation Authority Police, said those employees had some of the liquid on their boots and were monitored, but not injured.
The driver of the tractor trailer was not injured. No other vehicles were involved.
Green said Monday afternoon that investigators were still working to determine what caused the wreck. It was not immediately known Monday afternoon how much of the product spilled.
