The second span of the Madison-Milton bridge is scheduled for demolition at 9 a.m. Thursday.

Officials made the announcement Tuesday after originally saying the blast would not take place until next week.

The span that will be demolished is the 550-foot section nearest to the Milton side of the river. The section will be taken down in a similar fashion as the first section.

Sirens will again be sounded at intervals of 10, five and one minute before the blast.

The demolition will require the new bridge to close at 9 a.m. the day of the demolition. Crews will also have to close off streets within 1,000 feet of the explosion, which include:

In Kentucky:

• Milton boat ramp at KY 36

• KY 36 at Maple Street

• KY 36 at U.S. 421

• School Hollow Road at KY 36

• Coopers Bottom Road, 1,000 feet west of U.S. 421

• U.S. 421 at Coopers Bottom Road

• High Street from KY 36 to Coopers Bottom Road

• Alley between Swifty and carwash from U.S. 421 to High Street

In Madison:

• U.S. 421 at Second Street

• U.S. 421 at Fillmore Street

• Vaughn Drive between St. Michaels Avenue and Ferry Street

The new bridge and surrounding roads are expected to reopen to traffic at or before 11 a.m. River traffic will be closed starting at approximately 9 a.m. and will reopen at the same time as the roads.

Recreational boaters are required to stay 1,000 feet from the bridge during the blast. An FAA no-fly zone of 2,000 feet will be in effect prior to and during the blast.

Pieces of the truss will be retrieved from the river, placed on barges, taken to the shore for further dismantling and eventually sold for scrap. Divers are on call to ensure all pieces are removed from the river.
