SHA has been working on this $1.8 million project for most of the summer. It involves applying “whitetopping,” a bonded concrete, sustainable overlay,to the ramps. The special concrete improves breaking and makes for a smoother ride, according to SHA.More than 100,000 cars make use of the Rt.50/Rt. 301 interchange everyday, according to SHA.
