Here's what's stated in the statute noted by the O.P. (316.1945.1.a.6):
316.1945 Stopping, standing, or parking prohibited in specified places.—
(1) Except when necessary to avoid conflict with other traffic, or in compliance with law or the directions of a police officer or official traffic control device, no person shall:
(a) Stop, stand, or park a vehicle:
.
.
.
6. Alongside or opposite any street excavation or obstruction when stopping, standing, or parking would obstruct traffic.
I guess I'm not understanding what the "street excavation or obstruction" was in this particular instance.
