Walla Walla the town so nice they named it twice. Section 7, Map 99 of the ACA Lewis & Clark Bicycle Trail shows Detail A as crossing Hwy 12 at Lower Waitsburg Rd/N. Clinton St. This highway crossing is not open to pedestrians/cyclists. Coming in westbound on Middle Waitsburg Rd as you pass the airport turn left onto Blue Mountain Dr. and immediately right onto Rainer Dr./Wellington Ave. which will lead you under Hwy 12 and into Walla Walla. https://ridewithgps.com/routes/18002423
Can you give me more information about why this intersection is not accessible to cyclists and pedestrians? Has there been recent construction there? All images I can find on Google Maps and Bing seem to show it as an intersection without any restrictions.
I have looked at your suggested change and it does look more pleasant than that crossing. Would you continue on Wellington Ave. to Melrose St. and reconnect to the mapped route from there?
