The way points of this bicycle route:
Note excellent historic railroad tunnel under Wisconsin Avenue.
Trail is unpaved east of Bethesda. Possible on road bike. Keep your eye on the trail, though, for washouts and erosion.
Cross Connecticut Blvd. at the light.
Old railroad trestle has been rebuilt for the trail. If you have time, stop and enjoy the view.
This section of trail was substantially improved in June 2007. Still unpaved, but in much better riding condition.
There's a short connection from Stewart Avenue to Kansas Avenue. Easy to find; follow the signs.
1-lane bridge. Watch for the occasional car.
Busy crossing, but no problem if you wait for the light. 2nd Avenue is not a busy street. Good choice to get to central Silver Spring.
