Hello. I think this changeset and a couple others around this area overcomplicate/confuse some road classification criteria. Usually, it is fine for motorways to meet pedestrian crossings when they terminate at an at-grade intersection, especially when that intersection is a major one that indicates the end of the freeway. The only cases in which it is better to terminate the motorway at the interchange instead of the intersection is when the interchange is what indicates the end of the freeway, such as if the highway transitions into another highway or road that is not intended to be a freeway, like the Airport Connector or after passing through the terminals becomes Paradise Road or how the interchange east of the Hoover Dam marks the end of the bypass to become the original alignment of US 93, and there are no signs or signalized intersections which would better indicate that the freeway has ended. Additionally, regarding median breaks—these authorized access-only crossovers are essentially on every single divided highway, to allow emergency and maintenance vehicles to make safe immediate U-turns or for traffic to be switched over if urgently needed. It's very common for motorways to have intersections with various track and service roads that only authorized vehicles can use, and even sometimes even very minor publicly-accessible roads, usually unpaved ones.

As for Route 173, and the implication it should be trunk to eliminate a dangling spur, that is the reason I had downgraded it from trunk to primary in the past, as the freeway section of the 93 Business loop is only tagged at a motorway for its physical characteristic rather than its importance, and would be a primary road itself if it weren't built up to freeway standards between I 11 and VM Drive. In reality, 173 is only used to connect traffic between US 95 and I 11 into Boulder City, and is more of a local access road than a major long-haul highway like 95 or I 11.

Now regarding the Railroad Pass Casino Road—despite its freeway connection, it isn't necessarily used for getting between the two motorways (which is what 173 does further east) and doesn't serve any other secondary (or higher) tagged roads, but is rather only used for accessing one other tertiary road (Dawson Ave) and the commercial/industrial development right here at the interchange. In more rural areas like this, it will be more common and expected to have roads that connect to Interstates be tagged as tertiary and even unclassified/residential roads.
