ATLANTA -- Governor Nathan Deal had the news everyone has been waiting for since the I-85 bridge collapsed.

The newly rebuilt bridge will be reopened by Monday morning. How did they finish so quickly?

"Certainly, the incentives that were given to the contractor, C.W. Matthews, was one of the main reasons that we are completing this project well ahead of schedule," Deal said in a news conference.

The Georgia Department of Transportation said they spent $1.6 million to do the demolition along with $11.9 million to rebuild the bridge.

That's with at least $3.2 million in incentives – and possibly more depending on which day they re-open. The contractors get an extra $200,000 for every day they finish early.

Governor Deal says that's money well spent.

"I'm told that the estimated financial impact is about $27 million for having completed it earlier than the original projected completion date," said Deal.

The day after the collapse, the 11Alive Investigators explained how other states have used incentive programs in the past. California and Alabama had similar bridge collapses and, both times, the bridges were completed in less than 2 months.

GDOT said they are considering using more incentive programs on their other projects in the future which might speed up future construction.
