 With the opening of the facility, four older rest areas in Iredell and Yadkin counties, built in 1972-73, were closed.Interstate 77 is planned to have its existing southbound travel lanes widened (not add more lanes), between I-277/NC 16 (Brookshire Freeway) to I-85 in Charlotte.Estimated to cost $16.5 Million, the purpose of the project is to widen the lanes back to proper Interstate standards as agreed with FHWA, when NCDOT were given design exceptions when adding the HOV lanes in 2004.
