When the D.C. region was placed under a flash flood emergency a week ago, the National Weather Service indicated that some roads could be washed out by the destructive force of the floodwaters. The prediction proved to be accurate, and some flood-damaged roads may end up closed for weeks.
The District Department of Transportation reopened Canal Road between Reservoir and Foxhall roads late Monday morning. Erosion compromised a small culvert underneath the road near Fletcher’s Cove. A concrete slab and new pavement was constructed.
The Virginia Department of Transportation said it expects Prosperity Avenue south of Accotink Creek to be reopened in a matter of days. A low-lying section of the road, prone to flooding near a small run, sustained pavement damage.
In McLean, a rain-swollen Pimmet Run undermined a large section of Kirby Road. VDOT said the work to repair the road and embankment will take weeks. Part of the project will entail rechanneling the stream away from the roadway, a spokesperson for the agency said.
A heavily damaged section of Swinks Mill Road south of Georgetown Pike is expected to remain closed for months. VDOT said further assessments of the extensive road and bridge damage will be needed before repair work can proceed.
VDOT is assembling a specialty “strike” crew comprised of personnel from different maintenance yards to expedite the work on several other roads that were reopened in the days after temporary fixes were made. In total, about 15 roads will be addressed.
A section of Beulah Road near Wolftrap Creek and Leigh Mill Road near Difficult Run will need to be repaved. Erosion on the wayside of Georgetown Pike and Old Dominion Drive will be addressed as well.
