Considering that the intersection alternatives were presented to the public less than 48 hours ago, they sure must have had some blueprints in their backpocket! The intersection has mostly been torn up, gravel has been put down on the location that they will place a lane for traffic, and they have staked a second survey marker that they didn't know was there. It will definitely slow down their progress!
With another survey marker discovered, it is likely that a class 4 archeological assessment will have to take place.
And, of course, survey markers cannot be removed.
All this, and it is only 3pm, a day and a half after the public meeting for input.
Sort of confirms an earlier remark that the city just has these things to mollify the locals, and not to ask for any serious or well-considered, or thoughtful, or expert advice.
