 In 2011, MDSHA completed a study to examine constructing an interchange at Monocacy Boulevard on the north side of Frederick to replace the present directional crossover intersection.Design work then occurred on a diamond interchange with the municipal highway, which serves as a circumferential arterial in the northeastern part of the city.Monocacy Boulevard was extended west to north–south Thomas Johnson Drive and meet the eastern end of Christophers Crossing, which is a circumferential boulevard throughout northwestern Frederick.
