I live in Hays and I did the staking on Highway 183 from Hays to the Rooks County line a few years back. All of the RCBs were extended so the shoulders could be widened. The marks you are looking for are still there, they are just under several feet of fill. If you really want to find them, get a set of plans from KDOT or just look inside the RCB to see how long the extension was. Then measure back from the new headwall to the old headwall and start digging. Most of the marks would be set in the center of the headwall.
As far as setting up in an intersection to locate a point, well I do that everyday without any issues and I work by myself. In twelve plus years out here, nobody has ever messed with my base station.

Kent, I'm curious.....
The old 6"x6" concrete California Highway Commission monuments have a brass wire in the center to mark the point.
How would I go about the RTK solution? Is that just setting up a base and letting it sit for a while to get coordinates? I'm basically an uber-newbie to surveying. I know GIS and Remote sensing more than surveying.
