This plan would be an economic boon to New Castle, Delaware City, Port Penn, Leipsic, Little Creek, Bowers Beach, Milford, Lincoln, Ellendale, Georgetown, and Lewes.
Phase 1: Already underway. Georgetown to Lewes (rails to trails), and Lewes to Rehoboth (Junction and breakwater)
Phase 2: Follow Rt 9 south out of New Castle, connecting New Castle with Delaware City by way of an improved shoulder with rounded curbs to delineate car and bike/walking spaces. Then continue this way down to the Augustine wildlife area. Install alternating boardwalks and paths between Augustine and Cedar Swap wildlife areas. Then back to Rt9 south to Leipsic.
Phase 3: Rt 9 from Leipsic to Little Creek and then to Rt 352 toward Kitts Hummock. Existing road past Ted Harvey Conservation Area to a newly constructed foot/bike bridge over the St Jones River to Bowers Beach (probably the most expensive investment in the whole project).
Phase 4: South out of Bowers Beach on Rt 121 on a new bike/footbridge spanning the Murderkill river. 121 south (Thompsonville Rd) to Milford. South to Lincoln running parallel to the existing train line. Lincoln to Ellendale and Ellendale to Georgetown on the same easement.
Done.
