Massachusetts State Highway Routes

Interstate 190 (abbreviated I-190) runs for 19.26 miles (31.00 km) north from I-290 in Worcester, Massachusetts to Route 2 in Leominster, Massachusetts. A portion of the highway was built with extra-wide shoulders, which are painted green, to prevent runoff from contaminating the nearby Wachusett Reservoir. The green color is also intended to reduce the perceived width of the unusually wide road.

The entire route is in Worcester County.
