I'm not entirely sure, but according to records i've seen, the contractor that has paved the groom lake road may be CH2M HILL.

FWIW, the photograph also appeared on alt.conspiracy.area51. A few of the "investigators" still use usenet. Yes, frames suck. Also, firefox can get past the right click blocker. [Doh!]

Regarding the road, lets call it "sealed" rather than paved. I don't believe they put a stone base under the pavement.

There are bid requests from Nellis regarding paving, so I assume Nellis runs the contract. The TTR has had a paving request go out as well. The TTR, being less secret than Groom Lake, has also expanded its telecommunications capabilities

They did a similar sealing on Cedar Pass Road. No base, so the pavement erodes and you find dirt. It is almost worse than a dirt road because drivers try to steer around the failed pavement.

As far as I can tell, most road traffic to Groom Lake uses the Mercury Highway and passes through Gate 700 of the NTS. I met a truck driver that has taken deliveries as far as Gate 700. From that point, the commercial driver sits in the guard shack and a military (or at least approved driver) takes the truck to the base.

If you hang out around the front gate long enough, you only see cars and the bus. I don't ever recall seeing a heavy go down Groom Lake Road. Since the Janets don't fly on the weekends, you might find a base worker going into Alamo, so it is possible to see base traffic on the weekend.

The supposed contractor was probably listed as blackwater or other agency not identifiable with the contract work.
