The crosswalks, called “pavers,” were installed by the county on VDOT roads like Fairfax Drive, Lee Highway and Columbia Pike. They were built roughly 20 years ago as part of a county project to try to construct a brick-like crosswalk without material as fragile as the clay that bricks are made from.
“When brick sidewalks in old cities were in vogue, the industry developed concrete pavers as a flexible and durable surface for sidewalks that could adapt to tree roots without cracking and looked attractive in many areas,” county Department of Environmental Services spokeswoman Jennifer Heilman told ARLnow.com. “However, the heavy volumes of large vehicles such as what is typical of Fairfax Drive and most major arterials where Arlington has such crosswalks installed have made them very difficult to maintain as they’ve aged and become more prone to failure.”
