The highways formed parts of the old alignment of MD 216 on either side of Interstate 95 (I-95) in North Laurel in southeastern Howard County.

MD 983 had a length of 1.02 miles (1.64 km) and ran on the east side of I-95.

The state highway ended at the state–county maintenance boundary southeast of and adjacent to the MD 216–I-95 cloverleaf interchange.

Old Scaggsville Road continues as a county street that curves east before ending in a residential community.

[7] The highway was relocated to its present alignment from Main Street in Laurel to the site of the I-95 interchange in 1963, leaving behind much of what is now MD 983.
