It is illegal to ride on the sidewalk here, but while I was doing it a cop going the opposite way saw and didn't seem to mind. What is happening is the road way is two lanes on each side, plus a bike lane. On the side I ride on, the bike lane and both lanes are closed. The sidewalk is open. The traffic from my side is being directed (via orange cones) to one of the lanes on the on coming side. The construction guy said he wouldn't ride a bike through there and said to just use the sidewalk. I can't use a detour since this was a detour from my original plan. The detour sign from this street directed me back to the original road I can't use.
