Further Explanation:
North Carolina started building plank roads in the late 1840's. These roads were easier to maintain and easier to drive on. Before the plank roads were built, the roads had long muddy roads and large holes and ruts that drivers had to navigate through.
The crews could only lay an estimated 40 miles of plank roads per year and this did cause issues. North Carolina had the largest plank road with a total of 500 miles built. The rods failed after a few years because it took so long to build.
Citizens were then using the railroad system since it was faster than traveling by horse and buggy. The people also did not like having to stop at the toll booth that had been set up on the road. The money collected at the toll booth was used to pay for maintenance of the plank road.
