Three Rivers Park District (all of Hennepin County except Minneapolis) has posted on its website how the recent floods have affected its trails (here is a link with more information and the full list of closures). Here are the most notable closures for bicyclists:
Much of the section of the Lake Independence Trail paralleling Highway 12 in Baker Park Reserve is flooded.
The Luce Line Extension is closed between West Medicine Lake Drive and Xenium Lane due to a sinkhole.
The Minnesota River Bluffs LRT Trail is closed between Pioneer Trail and Highway 101 due to mudslides.
