Authorities say a semitrailer slammed into the back of a state highway department dump truck, leading to a section of Interstate 465 in Indianapolis being closed for more than three hours.
Two highway workers who were inside the truck were taken to a hospital with complaints of pain, while the semi driver suffered a non-life-threatening leg injury.
The crash happened about 2:30 a.m. Wednesday near I-74 on the city's southeast side as highway crews were doing maintenance work with the two right lanes closed. Police say that after hitting the dump truck, the semi ran into a highway department trailer carrying lighting equipment.
Southbound lanes of I-465 were closed until nearly 6 a.m. as spilled diesel fuel and crash debris was cleaned up.
