Brief History 

Written by Raymond Klein

It appears this bridge was originally constructed as a stone arch bridge. When the railrod right of way was widened they used concrete for the addition.
Have seen very few bridges that have a seperate bridge for the adjacant stream.
Two other bridges between Linfield, Pa and Pottstown, PA have a similiaer situation.
They were built with field stone and concrete and have adjacnt streams.
One is located on Sanatoga Road and the Sanatoga Creek goes under the bridge adjacant to the former road. The road is closed and covered with mud and originally lead to a bridge over the Schuylkill River to Chester county.
Then there is one on the former Porter Road and Sanatoga Station Road and near Pottstown,PA and Sprogles Run also goes under right next to Porter Road(now closed) which used to lead to and go under the Pennsylvania Railrod bridge at Pottstown, PA. Somebody told me he used to wash his car where the creek went under the tracks.
