1:15 p.m. Update: According to the Maryland State Highway Administration, Route 29 is open in both directions. Residual delays are possible.

Original post: Route 29 at Fairland Road in Montgomery County is closed this afternoon because of a fire in a work zone. Washington Gas is working to shut off a gas line that is apparently on fire, the Maryland State Highway Administration reports.

Detour for northbound traffic: Northbound Route 29 to Fairland Road to Briggs Chaney Road and back to northbound Route 29.

Detour for southbound traffic: Southbound Route 29 to Briggs Chaney Road to Old Columbia Pike to Randolph Road to southbound Route 29.
