Key Facts on Limeston Road in Wilmington
Limestone Road is a well-known roadway in northern Delaware and forms part of Delaware Route 7, a north–south highway that runs through New Castle County. The road serves suburban communities west of Wilmington, including areas such as Pike Creek, Milltown, and Hockessin, and is used daily by commuters traveling between residential neighborhoods and nearby business districts.
The Limestone Road segment carries Route 7 north from the Stanton and Marshallton areas toward the Pennsylvania state line. Along the way, it passes through a mix of residential, commercial, and suburban corridors, with sections that expand to four lanes to handle heavier traffic volumes.
Several major road connections make Limestone Road a key regional route. It intersects Delaware Route 2 (Kirkwood Hwy) in Marshallton and connects with Delaware Route 72 (Paper Mill Rd) farther north. Route 7 also links with Delaware Route 4 near Stanton and runs close to the Delaware Route 1 corridor, which provides access to Interstate 95, one of the main highways on the East Coast.
At its northern end, Limestone Road reaches the Delaware–Pennsylvania border, where the roadway continues into Pennsylvania and connects to Pennsylvania Route 41. This cross-state connection helps the road function as a commuter route between Delaware and nearby parts of Pennsylvania.
All in all, this road acts as a central transportation corridor in western New Castle County, linking local communities with several major state highways and regional travel routes.
