State Route 3

Home » Guides » Delaware » State Route 3

SR 3 runs north from the Edgemoor industrial area along the Delaware River to the Brandywine Hundred communities of northeastern Delaware. SR 3 also connects I-95 with the town of Bellefonte to the east and the village of Arden to the north. For the most part, the state route travels through residential areas as a minor arterial with two lanes. SR 3 expands to four lanes along the initial stretch of Edgemoor Road at Hay Road, I-495 and U.S. 13 (Governor Printz Boulevard) and through the interchange with I-95 at Carr Road

The initial alignment of SR 3 along Marsh Road appeared on the 1968 Official Delaware Highway Map northward from U.S. 13 (Philadelphia Pike) to SR 92 (Naamans Road) at Hanby Corner. The state route designation coincided with the completion of I-95 northward from Wilmington. The southern leg along Edgemoor Road was added by 1984. It included an overlap with U.S. 13 Business (Philadelphia Pike) between Marsh Road and Edgemoor Road, circumventing Marsh Road through the Gordon Heights and Edgewood Hills communities.

Following three years of construction, the parclo interchange linking SR 3 (Edgemoor Road) with Interstate 495 opened to traffic in June 1989. By 1996, SR 3 was realigned from another segment of Marsh Road to avoid the North Hills community. The change extended the SR 3 overlap with U.S. 13 Business (Philadelphia Pike) further east to Washington Street Extension, which returned the route to Marsh Road by Mt. Pleasant High School.
