Due to numerous public works infrastructure efforts in my area I twice just yesterday had to come about. One occurrence the officer apologized for an unanticipated already narrow road closure and asked me to turn around and said i could drive on the non-curbed sidewalk. I responded, "no problem, I won't need the sidewalk." After my very tight turn and departure I looked in the rearview mirror and saw his unmistakable look of "how did he do that?" appreciation.
