Point of Rocks Train Tunnel

First constructed in the 1860s, the tunnel was enlarged in 1902 to accommodate larger trains. In the early 1960s, the eastbound track was moved to the outside of the tunnel to accommodate still larger trains. This was done by blasting the rocks on the old alignment outside the tunnel, enlarging the road bed, and dumping the excavation rocks into the canal bed, where they remain today.
