WARREN COUNTY, OH (FOX19) -

Interstate 71 will be closed once again for several hours as crews will implode the remaining span of the old Jeremiah Morrow Bridge.

In order to complete the job, I-71 will close from the State Route 73, Caesars Creek exit to the Lebanon exit State Route 48 from 5 a.m. until 10 a.m. on Sunday, April 30.

It took ODOT officials two attempts last Sunday to blow up two of the four spans of the bridge -- which was recently replaced.

All four spans were scheduled to be blasted, but two of the spans were successfully imploded. However, there were issues with two spans:

On one span while all of the charges were detonated the blast did not fully cut through the steel supports as required to completely drop it, according to ODOT officials. The charges were reset and the span was successfully demolished.

On the other span only half of the charges detonated due to a connection issue with the original detonation.

The detour for southbound I-71 is State Route 73 to U.S. 42 to SR 48 to I-71; the detour for northbound I-71 is State Route 48 to U.S. 42 to State Route 73 to I-71.

During this detour, the ramps from State Route 123 to northbound I-71 and from Wilmington Road to southbound I-71 will be closed.

Also during this time, traffic on the Little Miami Scenic River and Trail will not be permitted between Wilmington Road and State Route 350.
