Delaware Route 141 (DE 141) is a state highway that serves as a western bypass of Wilmington, Delaware. Its southern terminus is at DE 9 and DE 273 in New Castle and its northern terminus is an interchange with U.S. Route 202 (US 202) and DE 261 in Fairfax. The route heads north from DE 9/DE 273 on four-lane divided Basin Road, becoming concurrent with US 202 at an interchange with US 13/US 40 and passes to the east of Wilmington Airport. The highway becomes a freeway and reaches an interchange with Interstate 95 (I-95) and I-295, at which point US 202 splits from DE 141. The DE 141 freeway continues north through Newport to Prices Corner. Here, the freeway segment ends and DE 141 continues northeast as a surface road, with another brief freeway segment in Greenville. The route heads east across the Brandywine Creek on the Tyler McConnell Bridge and continues to US 202/DE 261.
