First let me say this, it's time to do away with the "interim" Capital Crescent Trail. Either add it to the Capital Crescent Trail or call it the Georgetown Branch. And then be done with it - it's too confusing. But that's just my opinion.
The portion of the interim CCT east of the Rock Creek Trestle is in bad condition. It was never really in good condition, but erosion has made it worse. And people notice.
A recent DPWT inspection supports the recommendation made by the 2001 CCT/MBT Facility Plan - that this segment of the trail should be paved with asphalt to control erosion. The Coalition for the Capital Crescent Trail, WABA, MoBIKE and other trail advocates are calling on the County Executive and Council to fund this work in the next Operating Budget.
The problem, and proposed solution, is described in a slideshow, in PDF format.
I know that the idea is to leave this the "interim" section until the Purple Line is built, but honestly, that seems a long way off (if not forever). By the time the Purple Line is built, this section will probably need to be rebuilt anyway. I say pave it from the trestle to Stewart or Kansas Avenue.
