Travel directions

US 13 in Maryland comes from Salisbury and Norfolk and crosses the Delaware border at Delmar. The road has 2×2 lanes with a central reservation, and runs through a flat area to the north, with meadows and the occasional forest. After about 10 kilometers the first important intersection follows, the US 9 begins at Laurel, which runs towards Lewes. The road then continues north, past Seaford and Bridgeville, to Dover, the state capital. Dover has 36,000 inhabitants and is one of the largest cities in the state. From here begins the SR-1 toll road that runs parallel to US 13 to Wilmington in the north. The US 113. also ends here, the 2×2 trunk road from Ocean City in Maryland, which actually ran parallel to US 13.

At Delaware City, one crosses the Intracoastal Waterway, a wide channel that connects Delaware Bay to Chesapeake Bay. This is done via an arch bridge from 1942. You then enter an urbanized area, the first suburbs and overflow area of ​​Philadelphia, although that city is still about 75 kilometers away. US 15 also has 2×2 lanes here and is equally double – numbered with US 40, the main road from Baltimore to Atlantic City in New Jersey. One then crosses the Interstate 295, which the traffic fromWashington and Baltimore towards New York, thus avoiding the city of Philadelphia.

US 13 was created in 1926. The route has not changed significantly in Delaware since then. In the south of the state, US 13 is the main north-south route, but in the center and north, US 13 has now been bypassed by highways and has lost its through importance. In 1967 and 1968, I-95 opened around Wilmington, eliminating the continuing importance of US 13 here. Between 1987 and 2003, State Route 1 was constructed parallel to US 13 as a toll road. Due to the late construction, US 13 is almost everywhere with 2×2 lanes.
