Project Schedule/Updates

UPDATE: January, 2018 / February, 2018

Construction began the week of March 6, 2016.  Crews are currently installing 42" waterline from Ellsworth Road to the east. To date they have installed approximately 16,600 feet of pipe (only 3,500 feet left)!


The contractor continues installing the 42-inch waterline from Ellsworth to the east. As they get near the intersection of Signal Butte and Elliot, the barricade set-up will be modified. All traffic will be moved to the south side of the road and one lane in each direction and left turns will be maintained.

January 15, 2018 through January 19, 2018 - Left turns will be PROHIBITED for east and westbound traffic at the intersection of Signal Butte and Elliot. The manufacturer will be delivering more large diameter pipe.

There is ALOT of work going on in this area - so please slow down and drive with caution through the barricading!
