History • Interurban RailwayThe Joliet & Southern Traction Company (J&ST) line ran parallel to the Michigan Central Rail Road from Chicago Heights to Joliet. The trolley or interurban shared the right of way with the railroad for much of the length of the Old Plank Road Trail.The J&ST was a sister company to the Aurora, Plainfield & Joliet Railroad Company (AP&JRR). The AP&JRR entered Joliet from the west and connected to the J&ST in Joliet. J&ST tracks crossed the Michigan Central R.R. (now the OPRT) tracks in two locations. In downtown Matteson, the interurban built a bridge that crossed the Michigan Central and Illinois Central tracks at the same time.The map below shows the station stops along the lines of the two interurban lines.

Here's another picture of the bridge in Matteson over the IC and MC railroad tracks.
The J&ST trolley tracks ran parallel to the Michigan Central R.R. (OPRT) tracks from Chicago Heights to Summit, west of Frankfort. At Summit the interurban used a "fly-over" bridge to go to the north side of the trail. The concrete abutments for that "fly-over" bridge are about the only thing left from the interurban era. These abutments probably supported a light weight steel truss bridge similar to the one in the picture above.
