 Part of the Washington and Old Dominion Trail is about to get safer. Fairfax County Supervisor Walter Alcorn shared details in a video. I am here on the brand new bridge over Wheelie Avenue for the W&OD Trail here in Reston. This is very exciting. That bridge is set to open today, allowing pedestrians and bicyclists using the trail to avoid traffic. Fairfax Now reports the 16-foot-wide bridge has been in the works for years.
