A decade of construction has been hard on Williamsburg's sidewalks. Concrete poured for foot traffic gets crossed by trucks, dumpsters and machinery, and it fails at the curb line and driveways first. On top of that, many new buildings wrapped up with a temporary sidewalk that was never replaced with a permanent one.
The fix is to match the concrete to the load. Where vehicles cross, DOT specifications call for seven-inch reinforced concrete instead of the standard four-inch flag. We rebuild damaged crossings at full depth, replace temporary walks with permanent DOT-spec sidewalk and compact the base so the new work does not settle.
