Title: MD: MD 175 Extension West of US 29
Post by: Markkos1992 on December 17, 2019, 08:53:06 pm

It looks like MD 175 should be extended slightly west to the end of state maintenance at Little Patuxent Pkwy (https://www.google.com/maps/@39.2267234,-76.8524268,3a,75y,4.95h,90t/data=!3m6!1e1!3m4!1srwJTS6IXHgBped5h8QwpmQ!2e0!7i13312!8i6656).

Another situation of an arbitrary endpoint...

This appears to be right at the merge/diverge of the ramp gores. 1PPI, the interchange is understood to include the end of its footprint like this; this should be left alone.

Agreed - this is not unlike the several situations in Utah where state maintenance extends to the edge of the interchange footprint or even to the next intersection immediately past it. Unless it is explicitly signed as going both ways from the intersecting freeway (MD 175 is not), no need to include the little dangling end.
