It looks like the main lanes of I-85 in Atlanta have just collapsed due a large fire underneath an overpass. Rumor has it there were a bunch of those big spools stored under the bridge and they fueled the blaze.

Traffic is going to be...interesting.

This is a huge problem, as the corridor (I-85 and GA-13) carries almost 300,000 vehicles per day, including 222,000 on I-85 itself.

Hopefully the southbound bridge can reopen soon, perhaps detouring northbound traffic via GA-13 in a contraflow configuration. Edit: they say the southbound bridge is also compromised.

This incident reveals the vulnerability of the Atlanta freeway system, it has a small mileage for its population size, everything is funneled onto huge freeways, but if one of those is closed for a prolonged period of time, it results in massive congestion throughout the region.

An update was given concerning the I-85 bridge fire and collapse in Atlanta.

They say both the southbound and northbound bridges need to be replaced, 3 sections each. It could take months.

The main problem will be detouring that kind of traffic volume. GA 13 may reopen soon, it could absorb some traffic from I-85 but not directly from GA 400, and has only four lanes (it used to be I-85 until the current ten lane freeway opened in 1985).

The detour routes all end up on I-285, but the interchanges where traffic has to change from I-75 or I-20 to I-285 only have single lane connectors. Especially the northern part of I-285 is already notoriously congested even without an I-85 closure.

Long-distance traffic can easily bypass this section by using I-285, semi trucks are already obliged to take I-285 around Atlanta. So most traffic on I-85 likely has a destination or origin in and around Downtown / Midtown Atlanta. This means the arterial road system will absorb a major part of the traffic. People can only take so many days off from work, especially with a 'several month' event like this. MARTA recorded a 25% ridership increase.

This event likely exceeds the 2007 I-35W Saint Anthony Falls Bridge collapse in Minneapolis in terms of traffic impact. Minneapolis has a grid-like freeway system and relatively numerous alternate routes and river crossings. But the I-35W Saint Anthony Falls Bridge carried substantially less traffic at that time (around 150,000). During the rebuilding of the bridge, they converted an arterial road into a temporary freeway by blocking off side streets. I don't think that will be possible in Atlanta.

Reminds me of the 2008 Toronto Propane Explosion, but that was temporary.

Luckily no one was seriously hurt or killed in this collapse, right? I haven't seen that in the reports. That's a big plus.

The Toronto event just closed the 401 for a few hours, as the explosion itself was a couple hundred metres north of the highway. It was only done as a precaution.

The closure of I-85 is going to be a complete crapshoot on a scale that I don't think the US has really seen. Previous freeway collapses (I-35, Embarcadero) were lower traffic and far less important to the regional economy. Heck, they never even replaced the Embarcadero.

A quick count:

12 beams, 3 sections, 2 bridges. That's 72 beams total. 350 feet of bridge need to be replaced for each side. That is a total of 8,400 ft or 1.6 miles of beams that need to be manufactured on short notice.

That is why it will take several months to replace the six sections. Also, not just the beams and deck need to be replaced, but the support columns as well.

I-85, Atlanta

GDOT anticipates I-85 could reopen by June 15.

How do people in Atlanta cope? There are few alternatives along this route and they can't exactly all take a couple of months off. I expect to see an increase in MARTA ridership but not nearly to the extent of accounting for everyone that drives by there everyday normally.

Apparently MARTA has seen a 25% increase in daily ridership, which I believe means about 100,000, or around half of all I-85 traffic.

We're avoiding the area like the plague. A lot of businesses have been good about letting their employees work from home or shift their hours around. It sucks but we'll make it through.

What'd be interesting to see is how many people never go back to cars once the bridge is repaired.

I remember something similar happened 10 years ago in the McArthut maze, (a main conector btw San Francisco and Oakland bay bridge) a tanker truck crashed and exploded the fire melted the section above it and ultimatelly making it collapse during the night and next morning the traffic jam all over East Bay was epic!.. I can't believe it's been 10 years! and it happened around this time of the year too! April/29/2007.

http://www.nytimes.com/2007/04/29/us...-collapse.html


It took them just 26 days to rebuild it.
Here's a documentary, it's lover 20 min long but has some good insight and images while you fastforward.

The figure came at a time when both I-85 and GA-13 were closed, that's almost 300,000 vehicles per day (on average 360,000 people at 1.2 vehicle occupancy rate). However, it is unclear to me if that was systemwide or on nearby rail corridors. The two longest rail routes of MARTA happen to run alongside the affected corridors (I-85 and GA-400).

Yup. I suspect that number will decline as time moves on.

I wouldn't be surprised if a lot of people get in the habit of taking the train over the next 6 months and just keep at it afterwards though. Of course I don't expect that 25% gain to remain in place.. but it could decline to say, 5% and stay that way and I wouldn't be surprise.

Also isn't one direction of GA-13 still closed? It isn't much use if you can drive in during the morning rush but can't drive back.

That said, I'm looking at google maps traffic right now in the middle of rush hour (5:23pm EST), and traffic looks fine beyond the closure. Atlanta looks generally traffic free.
