Massachusetts State Highway 128

Route 128 is a ring highway with Boston at its center and surrounded by the concentric Route 495. Also known as the high-tech corridor, the area within Route 128 is the East Coast version of Silicon Valley, and is often referred to as "Route 128".

Route 128 makes more than a 180 degree arc around Boston, and clockwise is "North" even when the road heads slightly south of east when approaching the Atlantic Ocean. Hackers in the area refer to this as going "logical North" on the route.
