SR 42 formerly turned north on SR 100, following Walker Creek northeast to Staffordsville. There it turned east on current State Route 730 (now connected to SR 100 via SR 750, an old alignment of SR 100), following some smaller brooks and passing over a summit on its way to Eggleston, where it crossed the New River. SR 730 continues through a rather hilly area from Eggleston to its end at U.S. Route 460, from which US 460 follows Sinking Creek past Maybrook to the next piece of SR 42 near Newport.
