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. Portions of the highway are known as the Northern Bypass as well as Dr. Martin Luther King Jr. Highway.

The extension of AL SR 255 from near Pulaski Pike to Memorial Parkway/US 431 is proposed to be named Bob Wade Lane, according to Huntsville City Council.
