I google triped it from south at State Hwy 666 going north up route 19 to rt 668 then headed west to 113th and headed south all the way back down. Saw Trail Sport Bicycles, it got a little busy from 68th to 70th, a slight increase at Park but died out within a block, same with Village dr, once I got past Village the traffic almost disappeared till Johnson that became moderately light to moderate until 694 then dropped off again, shoulder to ride on was thin nothing uncommon for a lot of cities. I did notice one old guy riding on the sidewalk, is that something you could do if riding on the thin shoulder bothers you? Not sure when the camera vehicle went down that road but I didn't see any traffic that I would have been concerned about and I know that traffic I did see would be far less after midnight. The most dangerious night of the week is Friday night, people are tired and some are tired and drunk, so you may want to find another way to work on Friday just to be safe.

Route 113 heading in any direction has no shoulder to ride on except in small patches, I would feel far safer on 19.

If you haven't already bought some you may want to invest in some bright lighting both front and rear. If your bike has drop bars Soma makes bar end lights called Road Flare, they use a AAA battery instead of the button bats and those things are extremely bright. Combine that with a really bright tail light on the seat post or seat tube like the Cygolite Hotshot, or the Blackburn Mars 4, then add another to your helmet. Then up front get a nice bright head light, I'm partial to Cygolite headlights, they make a really nice ones that last and don't cost as much as other brands; then add a front flasher and a helmet light. The helmet lights or the front flasher don't need to be expensive. Use some reflective leg bands and tape on the helmet, plus reflective safety vest some riders wear though I never have. I don't know what you run for lighting but like I said you need to look like a christmas tree.
