** Update 5/22: it turns out that there is a bike nav sign at this intersection heading south, but it is set back about 200 feet from the intersection, so it is not very visible. Consider moving it closer to the intersection. JMM**
This is a request to Oakland Public Works to put in a bike nav sign on E 21St Street for southbound bike traffic, indicating that there is a bike route going uphill on 21st Ave. I frequently blow past that turn because it is unmarked. This is, as far as I can tell, the main bike-route way to get from downtown to the Dimond district, so I would imagine it would say “Dimond 1.6 mi”. You probably want to also label continuing south on E 21st St, although I’m not sure what the “destination” would be going that way (Foothill Blvd? San Leandro?). Video below at the intersection describing the issue further.
