So, you'd use the sidewalk beginning at 185th? I suppose as long as you are looking behind you when getting to the middle then looking to your right to cross again back onto the sidewalk. Then, stay on the sidewalk until it is safe to re-enter Baseline.

I have a similar situation. My express bus home drops me off at a terrible location and I must get off there. I walk my bike on a sidewalk for 1/8 to 1/4 of a mile to a safer location before getting on the street and riding home.

Good luck.

P.S. I saw this on google maps. It is an image of a rider slightly further east on Baseline. He doesn't look too worried. No helmet, riding with one hand, no high-viz gear. Looks like a safe road to me!
