Thank you for the reply.
It is pretty clear the road closure was not text book marked -- http://mutcd.fhwa.dot.gov/HTM/2003r1...0_longdesc.htm
This is also a tidbit I found:
"Section 6F.09 Local Traffic Only Signs (R11-3a, R11-4)
Guidance:
The Local Traffic Only signs (see Figure 6F-3, Sheet 2 of 2) should be used where road user flow detours to avoid a closure some distance beyond the sign, but where local road users can use the roadway to the point of closure. These signs should be accompanied by appropriate warning and detour signing."
As a result of the closure not being completely and correctly marked, I was not provided with the required information necessary to avoid the road closure.
"Section 6C.09 Detours and Diversions
Support:
A detour is a temporary rerouting of road users onto an existing highway in order to avoid a TTC zone.
Guidance:
Detours should be clearly signed over their entire length so that road users can easily use existing highways to return to the original highway."
[I'm more so taking notes here to gather materials]
