The Keith Line runs North-Northwest from the southern part of Little Egg Harbor Township, passing just north of Tuckerton. The line was to continue upward to a point on the Delaware River which is just north of the Delaware Water Gap, but Keith was stopped in his survey by Governor of West Jersey Daniel Coxe, when Keith had reached the South Branch of the Raritan River in what is now Three Bridges in Readington Township. To finish the border, Coxe and his East Jersey counterpart, Governor Robert Barclay met in London to set a compromise boundary called the Coxe-Barclay Line. More accurate surveys and maps were made to further resolve property disputes. This resulted in the Thornton Line, drawn around 1696, and the Lawrence Line, drawn around 1743, which was adopted as the final line for legal purposes.
