Long before the Warren Anderson Expressway. 

Urban renewal and other changes remade Downtown Schenectady in the past 65 years, but much of the old Stockade District remains the same.

Before Interstate 890 and the reconfiguration of Erie Boulevard in the city.

RIGHT - Circa 1996 with the old configuration of the interchange

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.
