Work on a couple of large city road projects are underway or soon will be slowing traffic. An extension of Joe B. Jackson Parkway, from the I-24 interchange to South Church Street, started last Monday. The two-year project, costing nearly 11-million dollars, will come out on South Church near the soon-to-be built Wal-Mart. This summer, construction will begin on Middle Tennessee Boulevard between East Main Street and Greenland. The pain will be felt around the MTSU campus for a couple of years while the road is widened with turn lanes, new sidewalks and more. This project carries a 12-million dollar price tag. In the meantime, motorists who use North Thompson Lane will continue to experience delays as milling continues, resurfacing begins and traffic signal installation continues at the Sulpher Springs Road intersection.
