The three drivers of the semis were sent to hospitals, state police said. One had a fractured sternum, one suffered scrapes and bruises and the third had a broken knee cap.
The two right lanes were closed for nearly four hours as emergency crews worked to clean up the crash, police said. By 8:35 a.m., all lanes had reopened.
