I found this archived forum thread from an Washington (DC) area group that might be helpful. They mention the Custis Trail.

We are just finishing the Lewis & Clark. The map panels have a elevation profile along with mileage chart.
Also on the map it would show mileage between point byway of black dots. These features are not on the Subject maps.
Slight seqway on this topic. How were the hiker/biker sites in California from SF south to the border? I've head that quite a few no longer have hiker/biker sites (eg South Carlsbad).
FYI...Just spoke [on the afternoon of July 22] with Fire information out of Winthrop/Twisp and was told the following:
1) fire had burned thru route 20 several days ago, not much left to burn
2) route 20 is currently open. It has been closed off and on over the last couple days so that utility crews could restore power lines, not because of smoke or fire.
3) he said that as an alternate if 20 gets closed again, we could take 97 to 153 and that those roads have been more open than 20 because of the larger number of people living in those areas.
In summary, as of now, we are planning on taking route 20 at Okanagan on Thursday [July 24] heading towards Twisp. Here is the Fire Info contact number tel:509-996-9971 if you want to call to get the latest updates. The number is open from 7am-7pm.
Early quit no doubt.
BTW...Tim Carey, the Travelling Bike Nurse, who you may know (I know some of your staff does) is an aquainance of mine. Early this month he rode up north into Canada. Not sure if he's still north of the border or headed back here.
As I think I noted in my trip report, United Airlines is to blame for my late arrival. I did stop in on 6/28 around noon. Only two people in the office. Already making good use of my Bikelingual bandana.
