I was surprised looking at the assessment records that the hamlet of Rotterdam Junction is newer then I would have thought. Most of the hamlet was built between 1900 and 1950, with many of structures from the turn of century. There also newish subdivison built off of Alexander Drive that was built in 1980-1982 and Ulrich Road that was built in around 1993, with a few luxury houses added in 2003-2004.

While not yet built it's obvious that Pleasant Valley was being actively mined in preparation for construction of the future arterial highway.
