As the concrete crews worked their way from north to south along Percy Julian Drive Friday, the surface's final white color lagged a couple hundred yards and a couple hours behind. Crews paved a single strip nearly the entire street wide from Washington Street to the Greencastle Middle School entrance. Work will continue Monday as the rest of the road and the entrances to the school parking lots are paved. Once the paving is done, it will take another four days before the concrete can bear the load of vehicle traffic.
