MD 824 was assigned to the old road after US 222 was relocated for its interchange with Interstate 95 (I-95) in the early 1960s.

MD 222 heads south toward the I-95 interchange as Perryville Road and west as Bainbridge Road toward Port Deposit, and MD 275 heads north as Perrylawn Drive toward Rising Sun.

[4][7] The highway was proposed to be widened to 20 feet (6.1 m) in 1934, and that expansion came between 1942 and 1944 when US 222 was expanded to improve access between US 40 and United States Naval Training Center Bainbridge, east of Port Deposit.

[4][8][9] MD 824A was assigned to the highway after US 222 was relocated for its interchange with I-95 when the freeway was constructed in 1962 and 1963.

MD 824 (without suffix) was the designation for Weaver's Corner Road, which extended for 0.05 miles (0.080 km) parallel to US 222 between a pair of dead ends on both sides of Old Conowingo Road at Oakwood.
