[T]he new I-40 alignment is supposed to be several feet below grade level except for the minor detail that there’s not enough support for the actual roadway that far down.
I left it at that, but Nick Roberts has the gory details:
Basically, this whole I-40 project has turned into a disaster. Not only is it experiencing un-Godly cost overruns, but it was supposed to be an entirely depressed freeway like the Connector through Downtown-Midtown Atlanta. Well, surprise, there’s a water table. So now it will only be 8 feet depressed, which means that I could stand up against the edge and easily touch the grass up on the ground. There are trucks that are at least 12 feet tall, and my suv is about 8 feet tall to put into perspective how “depressed” this highway will be. The result is that we basically have an at-grade freeway and not a depressed freeway, which may cause this Core to Shore thing to need some complete rethinking. So much for removing a “barrier.”
I’m depressed just thinking of the cost overruns. We’re not at Big Dig levels yet, but we’re working on it.
