  • 6-12-18 - Rott Rd. is closed.  Above & Below (A&B) is on site and starting construction activity in the work zone.  A&B is hand digging to expose known utilities in the area.  This process is known in the construction trade as "potholing."  They are doing this before commencing with larger scale excavation work involved to replace the retaining walls and storm sewer piping.

  • 6-18-18 - A&B has the north structure set.  They removed rock for this on Friday until about 2pm.  Today the plan to de-water the upstream hole, dig out the pipe crossing below the road and set the new pipe.  The old wall still requires removal.  Rain is predicted in the area from Wednesday through the weekend.  A&B would love to have the new pipe in place before the rains come.
  • 6-19-18 - A&B continues with pipe installation in hopes of beating the forecast rains.  They continue to encounter Rott Pipebedrock with pipe installation.  They are about 1/2 way across the street moving toward the old rock wall as of 8am this morning.
