(Updated at 5:00 p.m.) Many of the sidewalks built over the last two years in Arlington are already crumbling, and the county is trying to figure out why.
At least a dozen sidewalks all over the county — like the ones pictured above — appear significantly damaged, their surfaces crumbling and creating tiny pieces of debris. These are not pieces of aging infrastructure that plague the county, these are recently installed sidewalks that have worn down rapidly.
