No, definitely not a part of the MLK project. I was surprised to see all that too....considering folks on our main road drive down the middle to avoid the many holes and patches on either side.
I've heard that Goldmine is going to be rerouted to accommodate the airport expansion but also heard it was only going to be closed a few weeks. That doesn't make sense so I'm really not sure. It was supposed to be closed yesterday, but wasn't.
