History

In 1852, local entrepreneurs began construction of the Wills Valley Railroad through town as part of the route between Chattanooga, Tennessee, and Elyton, Jefferson County; construction was interrupted by the Civil War and resumed in 1870. In 1877, it became known as the Alabama Great Southern Railroad. Passenger service ended in 1970, but the line still operates as a freight carrier run by the Norfolk Southern Railway.
Collinsville was heavily damaged by fire twice, once in 1884 and again in 1900. The 1900 fire destroyed all but three buildings in the downtown area, burning some 27 businesses in all. Flooding from the Little Wills Creek was also a problem in the downtown area until extensive work on the creek channel and levee and flood wall construction was completed in 1939.
