. The Penns later acquired the New Castle lands from the Duke of York, which they called the Three Lower Counties and are now known as Delaware. Delaware, however, remained a distinct possession from Pennsylvania.

, and tried to make claims to the land south of Philadelphia. The Calverts had failed to confirm their hold on their grant, either by surveying it or by establishing loyal settlers. The main progress through the 1750s was to survey the famous Twelve-Mile Circle around New Castle as the northern and western boundary of Delaware, and to establish the Transpeninsular Line

  5. Should any land within the Twelve-Mile Circle fall west of the North Line, it would remain part of Delaware. (This indeed was the case, and this segment is known as the Arc Line.)


When this was agreed upon, no one knew what the final shape would really be. Mostly due to the difficulty of surveying the Twelve-Mile Circle tangent point and the Tangent Line, astronomer Charles Mason

. It turned out that there is a small wedge of land between 39° 43' N latitude, the Twelve-Mile Circle, and the North Line. The top is roughly 0.75 miles (1.2 km), and the side is roughly 3 miles (4.8 km) long. Clearly Maryland no longer had a claim to the Wedge, as it is east of the Mason-Dixon Line and as both Pennsylvania and Delaware were owned by the Penns, there was no particular incentive to determine which possession it was a part of, at least until they became separate states.
  • Pennsylvania claimed the Wedge because it was beyond the Twelve-Mile Circle and past the Maryland side of the Mason-Dixon Line, therefore neither part of Maryland or Delaware. So by default it should be part of Pennsylvania.
  • Delaware claimed the Wedge because it was never intended that Pennsylvania should go below the northern border of Maryland (which originally ran at 40° N all the way to the Delaware River). The North Line is logically an extension of the Tangent Line and therefore should separate Maryland and Delaware. Even though the Wedge is outside the Twelve-Mile Circle, because it is south of the 39° 43' N compromise line, it should not be part of Pennsylvania.


Mason and Dixon actually began surveying the Maryland-Pennsylvania border line at the Delaware River, or at least fixed the longitude of the intersection of 39° 43' N and the river. Even though this point is within the Twelve Mile Circle, the western boundary of Pennsylvania was to be five degrees of longitude west of it, and Mason and Dixon were to survey the Maryland line to Pennsylvania's western border.

By simple merits of the geometry, the Wedge more logically fit as a part of Delaware, which exercised jurisdiction of the area. In 1849, Lt. Col. J. D. Graham of the U.S. Corps of Topographical Engineers resurveyed the northeast corner of Maryland and the Twelve-Mile Circle. This survey reminded Pennsylvania of the issue and they once again claimed the Wedge. Delaware ignored the claim. In 1892, W.C. Hodgkins of the Office of the U. S. Coast and Geodetic Survey monumented an eastward extension of the Maryland-Pennsylvania border, and created the "Top of The Wedge Line". In 1921 both states settled on this boundary.

Contemporary routes

Delaware Route 273 and Delaware Route 896 cut across the Wedge. Route 896 passes very close to the tri-point, and actually passes through Maryland before entering Pennsylvania, while Hopkins Bridge Road, a side road off of Route 896, passes near the northeast corner of the Wedge.
