View an article about the construction of this bridge.
This is a massive two span deck girder crosses what was formerly a mill race, now the Ice Age Trail in Janesville.
Built in 1900, the bridge consists of two massive deck girder spans, set onto concrete abutments and a stone pier. The girders themselves are each 115' long, extremely long for early 20th century construction.
The stone pier is also unusual, as the abutments are constructed of concrete. The bridge was constructed as the Milwaukee Road began to switch from stone to concrete substructures.
Between 2014 and 2017, the two concrete abutments were encased in concrete as part of a rehabilitation of the bridge, which also included a new deck.
