3 sections north and 3 sections south will have to be replaced - "several months".  And all this on a section of interstate that is used by 225,000 vehicles per day.

What engineering phase? You just pull up the final plans from the original construction, mark the areas that need to be replaced, and place an emergency advertisement for bids. The only problem would be if FHWA or the state legislatures are being difficult. Having both directions shut down actually makes it easier. No lookie loos and boy racers to deal with. We did a similar section after Katrina in three weeks. 

LOL!

So, I will assume there is collateral damage to the surrounding and existing structure. There will need to be some pretty good inspections done to determine the extent of demolition required. Then there will need to be engineering done to determine the affect of the demo on the structure to remain. Then there will need to be engineering done and submitted by the contractors after the documents are prepared and the bidding is complete that show exactly how they intend to demolish the structure. This will include weights procedures, handling of materials etc. It's not quite as simple as one might think. If you close the whole thing down and completely demolish the entire structure and rebuild, it will be faster, but three weeks is ridiculous. These materials aren't just sitting on a shelf at Menards. Beams have to be made. It would be irresponsible not to have oversight and review of the construction. That's how things fall down. 

I will bet you a beer that I'm closer than you are.

I did this work as a Civil Engineer for 35 years for MDOT. The prestressed beams are a standard stock item, so is the concrete and steel. The beams are standard sizes and can be shipped in from surrounding states, they actually take a week to make but our prestress plant usually has some in stock. The regulations as to construction and demolition are in the state Manual of Standard Specifications. The original plans include the concrete and steel needed per linear foot of deck, the bearing pads that were used etc. If GDOT can't evaluate the extent of the damage in a week or less then Georgia really has problems. Personally I think they can though.The contractor will have to submit the beam grades in order to allow for construction sag but that can be done in days while the materials are being shipped in. As to the oversight that is the responsibility of GDOT and they employ engineers and technicians.

Doesn't work that way in Illinois. Hell, just the bolt testing would take 8 weeks. Ain't nothing standard or stock up here. Offer stands for a beer. I hope you are right BTW.

This hasn't been mentioned, but was it a Sherman tank that set fire to the bridge?

I figured the bridge was stressed from all of the Yankees that are flocking south to escape the northeast. 

I have hung up my commuting for the foreseeable future....  Airport or College Park MARTA station for me to the Medical Center station....  Still took an hour on the train, plus a 1/2 mile walk from the station to my building.....  I might be skinny by the end of the summer!!!!!

Are there rules about concealed carrying on MARTA?  I guess I should look that up!!!!

Yankees fans are the WORST!

The Russians did it, no it was Bush's fault, yeah that's the ticket ! But we do have the 2 newest stadiums on the planet !

Well that's because in our great stat of Illinois it takes politicians a week just to tie their own shoes.

They don't tie their own shoes, silly.  Politician shoe-tyer is a union job with full pension&medical after 7 years.
