The three mainline sections of MD 662 pass through the villages of Longwoods, Skipton, and Wye Mills as they parallel US 50.

The three main sections of MD 662 were designated in 1948 following the construction of US 50's bypasses of Easton and Wye Mills.

The highway passes between residences on large lots before entering a forested area and crossing Skipton Creek.

The highway veers north and then northwest, crossing another creek and passing through the hamlet of Skipton before reaching its northern terminus at US 50.

[5] MD 662 was assigned in 1948 to those segments when Easton and Wye Mills were bypassed with a straighter highway that in 1949 became part of an extended US 50.
