Catawba Bridge repair closing seven river accesses in three communities River accesses closing due to bridge repairs in York County By Morgan Newell | April 22, 2021 at 6:25 PM EDT - Updated April 22 at 6:25 PM TEGA CAY, S.C. (WBTV) - Mark your calendars because just two weeks from Thursday, the major repair work will start on the I-77 Catawba River Bridge in South Carolina. While, it will create a lot of headaches for drivers, it will restrict people being out enjoying the river too. At first, hanging out on the river during the construction was not going to be an issue. However, Rock Hill, Fort Mill, Tega Cay and York County officials agreed it would be better to keep swimmers and fishers away.
