By the way, the River Trail is mapped as a combined cycle and foot path by bicycle=designated and foot=designated. So because it is combined, highway=path should be used over highway=cycleway, unless you prefer to map the sections where they are actually segregated within MSU as two separate paths, in which case you can map the bicycle portion as highway=cycleway and the foot portion as highway=footway. Until then, please keep the River Trail as highway=path (or start a discussion about this amongst other Michigan mappers). 

The page for Michigan on the OSM Wiki states "Most trails and paths in Michigan are multi-use. Often with rules posted specifying foot traffic has the right-of-way. These are NOT cycleways. When in doubt start with highway=path." See here: https://wiki.openstreetmap.org/wiki/Michigan#Paths_/_Trails
