The Camden and Amboy Company having obtained control of the steamboat
routes between Philadelphia and Bordentown, and between South Amboy
and New York, directed their energies to completing the railway across
the State.
Although the grading of the road from Bordentown to Camden had been
commenced in the summer of 1831, work on that end of the line was
abandoned for about two years, the entire construction force being put
on the work between Bordentown and South Amboy.
The road from Bordentown to Hightstown was completed by the middle of
September, 1832, and from Hightstown to South Amboy in the December
following. The "deep cut" at South Amboy, and the curves of the track
there, gave the civil engineers great trouble.
