I-5 direction of travel
I believe that the City of Vancouver and maybe PDOT are worknig on signing the bridge paths as directional in the near future. They are currently producing a map, which I have commented on, to educate the public on the routes between Vancouver and Portland through Delta Park & Jantzen Beach, as well as signs to indicate direction for bikes, and route signage. Peds will not be restricted to one side or the other. Vancouver plans to post a permanent map on the north side. Don't know if Portland will post a map or not. This probably is all dependent upon funding, as usual.
