The south approach

The narrow lane was the Lincoln Highway for many years. The bricks are original paving and this block is one of only a handful of places in the country where original Lincoln Highway brick paving is extant.

Railing detail, looking east

This bridge was closed in 1996. The UPRR (UP acquired the C&NW in 1995) wanted the bridge torn down, because for many years, students of nearby Cornell College were accused of throwing rocks at passing trains. The bridge was renovated over 1997-1998.
