 As part of this project, the oblique intersection with MD 806 on the north side of Thurmont was removed.MD 806 was moved onto Albert Staub Road, which was extended north over a new crossing of Owens Creek to its present terminus at Roddy Creek Road, where local traffic could access US 15 at a perpendicular intersection.The two-lane highway between Lewistown and MD 550 was expanded to a four-lane divided highway in 1985.
