MDSHA conducted its first study on expanding US 113 north of Berlin to a divided highway in the early 1970s. Although US 113 was not expanded at that time, preparations for a future expansion were started, including acquisition of right of way along the proposed route. When MD 90 was built from US 50 to east of US 113 between 1973 and 1976, its interchange with the future course of US 113 was partially constructed. MDSHA conducted a second planning study in the late 1980s; in 1990, the agency decided to implement intersection improvements instead of constructing a divided highway. One particular improvement was reconstructing the highway immediately to the south of the Delaware state line to better tie into the divided highway in Delaware in 1989 and 1990.
