After separating from the beltway, I-83 is now known as the '''Baltimore–Harrisburg Expressway'''. Running due north away from the beltway, the route parallels [[Maryland Route 45|MD&nbsp;45]] (York Road), the former route of [[U.S. Route 111|US&nbsp;111]]. Passing to the west of [[Timonium, Maryland|Timonium]] and [[Cockeysville, Maryland|Cockeysville]], I-83 leaves the suburban belt around Baltimore and enters rural Baltimore County just north of [[Hunt Valley, Maryland|Hunt Valley]] at [[Shawan Road]]. I-83 and MD&nbsp;45 continue to parallel one another through the northern portion of the county, with MD&nbsp;45 crossing over I-83 once, at an interchange. This segment of I-83 has several sections with higher than usual gradients.

The only major settlement encountered by I-83 along this stretch is [[Monkton, Maryland|Monkton]], reached via [[Maryland Route 137|MD&nbsp;137]]. To the west of I-83, MD&nbsp;137 connects with the northern terminus of MD&nbsp;25, I-83's former companion to the south.

The Interstate eventually crosses the [[Mason–Dixon line]] into [[York County, Pennsylvania]], {{convert|25|mi|km}} north of Baltimore, mere feet from a partial interchange with [[Freeland Road]] and parallel with MD&nbsp;45; the latter route becomes the [[Susquehanna Trail]] when it reaches Pennsylvania.
