Research Park Boulevard (State Route 255 or SR 255) runs from I-565 to Bob Wade Lane on the north and west sides of Huntsville in Madison County, Alabama. Much of the route is a limited access highway, with the entire route planned to be limited access. Plans call for the road to be extended to create a near-complete bypass around Huntsville.
