[15] Corydon is served by Iowa Highways 2 and 14 which make up the southern, eastern and northeastern portion of the town square.

Rail service through Corydon is provided by the Union Pacific Railroad.

Since the Union Pacific merged with the Chicago and North Western Railway (C&NW) in 1995, there has been a considerable increase in rail traffic on the line.

After the Rock Island ceased operations, its main track between Kansas City and Allerton was combined with the Short Line to form C&NW's "Spine Line" between Kansas City and Minneapolis and that designation has been retained by Union Pacific.

The Rock Island depot was removed in the late 1950s with passenger service provided through Allerton, six miles to the southwest until about 1970.
