Question

Why does interstate 95 seem to follow the fall line?

It was designed to go around waterfalls and rapids

The fall line is flat and was easy to construct a road on

Abandoned railroad tracks share the same route

It connects cities that were established on the fall line

Answer 1

Interstate 95 seems to follow the fall line primarily because **it connects cities that were established on the fall line**. The fall line is a geographic boundary where the hard, crystalline rocks of the Piedmont region meet the softer sedimentary rocks of the Coastal Plain. This area often features waterfalls and rapids, and historically, it was a key location for early settlements and cities. These cities were often built near the fall line to take advantage of the water power for mills and industries. As a result, Interstate 95, which connects several major cities along the East Coast, aligns closely with this historic route through the fall line region.
