The town was separated into north and south sections when the C&D Canal was built through the middle of the town. The two were connected by a drawbridge until 1942 when that was destroyed by a freighter that struck it. The current bridge opened in 1949.
The new bridge had to be tall enough to allow supertankers to pass beneath it, resulting in a structure so high and long that cars no longer went into the city to cross the canal. Business declined for decades thereafter.
Nothing in the archives for these yearsWeddings on Main Street, storms, parades, school pictures, the old store. If it’s in your family album, it belongs here.
Fire insurance maps drew every building, what it was made of and what it was used for, so insurers could price the risk of fire. Pick a year, then a sheet.
