I-65/I-70 South Split

Indiana Department of Transporation (INDOT)

Project Description:  More than 400 collisions have been recorded at the South Split bridges over I-65/I-70 since 1999 and the frequency of vehicle bridge strikes has increased in recent years.

The I-65/I-70 South Split project will reconstruct and lower one-half mile of pavement beneath seven bridges.  The project is necessary to increase bridge clearances and reduce the potential for collisions from unpermitted and off-route trucks with oversize and unsecure loads.  Repeated bridge strikes from these trucks continue to pose a safety concern.

The bridges at Virginia Avenue, Fletcher Avenue, Calvary Street, and Morris Street have vertical clearancees ranging from 13 feet 11 inches to 14 feet 6 inches.  This project will increase the vertical clearance of each structure to at least 14 feet 9 inches by reconstructing and lowering the pavement.  The new pavement was built of continuously reinforced concrete, which is held tightly together with reinforcing steel and does not require contraction joints.  This pavement will withstand traffic loads and adverse environmental conditions, decrease maintenance, user delays, and remain in service well into the next generation.

United designed northbound lanes of I-65/I-70 from the split (south of Virginia Avenue) to just north of Fletcher Avenue as well as the beam replacements for NB and SB Virginia Avenue bridges.

INDOT closed the interstate throught the work zone in order to accelerate construction and expedite completion of the project while providing a safer environment for workers and motorists.  The project was completed in 44 days, two weeks ahead of the 59 day schedule.
