FORT MILL The Fort Mill boat access ramp at Lake Wylie Dam should be open by early next month, complete with several improvements. The ramp was shut down earlier this month for renovations. Its a total upgrade to that facility, said Tim Pettit, spokesman for Duke Energy, the company that manages the Catawba River. Includes are fishing platforms, a walking trail, an upgraded boat launch and improvements to the turnaround, including paving. Construction should be complete by the end of this month, with the boat ramp reopening shortly after. Were still on track, Pettit said. Rains slowed us down a little bit, but we still expect that thing to be open the first of May.
