The west leg of the intersection is unsigned MD 795, a connector between the intersection and the northern end of Interstate 795 (I-795) at MD 140 that allows Baltimore–Hampstead traffic to bypass the center of Reisterstown.

MD 128 heads east as a two-lane undivided road through the community of Glyndon, where the highway crosses over CSX's Hanover Subdivision railroad line, passes through the Glyndon Historic District, and meets the northern end of Central Avenue, a northern extension of Owings Mills Boulevard.

MD 128 continues northeast through horse country, passing to the northwest of Sagamore Farm.

[4][5] The remainder of the route between Worthington Road and Reisterstown included county-maintained Butler Road west to Glyndon and MD 127, which followed Chatsworth Avenue from U.S. Route 140 (now MD 140) in Reisterstown east to the Western Maryland Railway tracks (now CSX's Hanover Subdivision) in Glyndon.

[5][6] In 1948 and 1949, MD 128 was extended west over Butler Road and a new bridge over the railroad to its present western terminus.
