Here is a link to the .pdf for the RFP issued for the lengthening of runway 06/24 at the GMIA to 10,000 ft.

Note that they have mandated a completion date of December 1, 2013. The document contains a diagram of the project. The end of the runway will be very close to the TCH. You can also see the extension to Aviation Blvd, and how it will extend a considerable distance beyond Malley Industries. The road will run between the end of the runway extension and the TCH. I believe the eventual plan may be to have an interchange directly from Aviation Blvd to the TCH. Perhaps
Myles can confirm this.....
