Dover to New Castle Road Trip: A Guide to Delaware's Scenic Byway

Did you know that the stretch of US-113 from Dover to New Castle was originally part of the Dupont Highway, a private toll road built by the Dupont family in the early 20th century? This 40-mile corridor, now largely free, connects Delaware's capital with its historic colonial port. The drive offers a microcosm of the state's geography: flat farmlands giving way to suburban sprawl, with the Chesapeake & Delaware Canal bisecting the route near St. Georges.

The best stops Dover, DE to New Castle, DE include the Bombay Hook National Wildlife Refuge and the Historic New Castle Court House. For things to do between Dover, DE and New Castle, DE, plan a walk through the St. Georges Bridge overlook.

Natural landscapes along the route are dominated by the Delaware Bay estuary. Bombay Hook National Wildlife Refuge (8 miles east of Smyrna) features tidal salt marshes, freshwater impoundments, and upland forests. Over 300 bird species have been recorded here, including bald eagles and egrets. The refuge has a 12-mile auto tour route and several boardwalks.

Further north, the St. Georges Bridge area offers a view of the Chesapeake & Delaware Canal, a man-made waterway linking the two bays. The canal's banks are lined with trees and are a good spot for heron watching. The route passes through the Delaware River watershed, with subtle elevation changes rarely exceeding 50 feet.

Local commerce is concentrated in Smyrna and Odessa. Smyrna has a small downtown with antique shops and a diner. Odessa is known for its historic district, including the Wilson-Warner House (circa 1769) and the Corbit-Sharp House, both open for tours. New Castle's Battery Park offers a view of the Delaware River and the large oil tankers at the Delaware City Refinery.

For a cultural visit, the New Castle Court House Museum (first state capital) is a must. The town's cobblestone streets and old taverns give a colonial feel. Local artisans sell handmade pottery and jewelry at the New Castle Farmers Market (Saturdays).

Begin in Dover at the intersection of US-113 and DE-1. Follow US-113 north, which becomes DE-1 after the Smyrna interchange. The road is well-paved with frequent gas stations near major intersections. The Chesapeake & Delaware Canal bridge at St. Georges is a notable landmark with a 65-foot clearance.

Fuel costs average $3.20 per gallon, and efficiency is high as the terrain is flat. Plan to refuel in Dover or near the Delaware City junction. Restrooms are available at most gas stations, but the Smyrna Rest Area (mile 15) offers clean facilities and picnic tables.
