MD 373 has been reconfigured at MD 5.
It no longer crosses MD 5 at all. instead, there is a roundabout just west of MD 5 with a ramp to MD 5 SOUTH. MD 373 now turns north on a newly constructed road alongside MD 5's SB lanes, crosses Brandywine Rd (which also no longer crosses MD 5) and meets up with MD 5 at the interchange at Spine Rd. OSM shows the Spine Rd overpass but not the new 373 alignment alongside MD 5 SB lanes. Google Maps and GMSV mostly show everything if you want to see a visual of what is now in place.
