These are Pre-Final plans, so they seem very far along for public comment to make any meaningful changes. One thing I noticed is that this will be an extremely steep trail (13% to 14% grade).
The project looks redundant from a ped/bike standpoint as the shared-use path along Oakwood Rd offers a much safer, more comfortable alternative that takes you to the same spot and doesn’t involve crossing a I-495 on-ramp at-grade (although this crossing will be signalized). I still wouldn’t want to hang out for 2+ min in that corner while traffic zooms past me waiting for this crossing signal.
