Delaware Route 3

Delaware Route 3 (DE 3) is a state highway northeast of Wilmington in New Castle County, Delaware. The route runs from an interchange at Interstate 495 (I-495) in Edgemoor north to DE 92 in Brandywine Hundred. The route passes through the suburban areas of Brandywine Hundred, Bellefonte, and Arden. It intersects U.S. Route 13 (US 13) in Edgemoor, US 13 Business (US 13 Bus.) in Bellefonte, and I-95 near Bellevue State Park. DE 3 was built as a state highway during the 1920s and 1930s. By 1968, the route was designated between US 13 (now US 13 Bus.) north to DE 92 on Marsh Road. The route was moved to its current alignment and terminus by 1984.

Route description

DE 3 begins at an intersection with Hay Road at an interchange with I-495 in an industrial section of Edgemoor, heading northwest on four-lane divided Edgemoor Road. After the I-495 interchange, the road passes over Amtrak's Northeast Corridor and intersects US 13 in areas of businesses. Past this intersection, DE 3 enters a more residential area as a three-lane undivided road with two southbound lanes and one northbound lane. The route narrows to two lanes and turns west and north, coming to an intersection with US 13 Bus. At this point, DE 3 turns northeast to form a concurrency with that route on four-lane undivided Philadelphia Pike, running through residential and commercial areas. DE 3 splits from US 13 Bus. in Bellefonte by turning northwest onto Washington Street Extension, a four-lane divided highway. The route turns north onto Marsh Road, a four-lane undivided road that forms the western boundary of Bellevue State Park. The road becomes a divided highway as it comes to an interchange with I-95.
