Bridge officials announced Tuesday that the slide has been tentatively set for Sunday morning.

Crews will continue to install harness assemblies and work on other final preparations throughout this week as weather allows, Indiana Department of Transportation spokesman Will Wingfield said.

"There's still a lot of work being done to prepare for the slide," he said.

Rain forecast this week could delay the slide if weather keeps crews from completing the final preparations by Sunday morning.

The nearly half-mile steel truss will be slid 55 feet onto refurbished piers. The entire slide is expected to take approximately 16 hours to complete.

The bridge is expected to reopen about a week after the slide when crews complete work on the approaches, concrete work and inspections.

Officials expect the bridge to remain closed until mid-April.

Bridge officials also said the emergency ferry for ambulances and other emergency vehicles will be suspending runs each day after dark due to elevated river levels and debris in the water.

Existing medical helicopter services will be available for critical emergencies, the release said.
