• Contractor nameTBD
• Completion DateNovember 14, 2025

Project Update: 02/18/2025

This construction project is the first phase of the City’s third connection to the Lewis & Clark Regional Water System. A 24” PVC water transmission main will be installed along Ellis Road from Windmill Ridge Street north to 12^th Street (Highway 42), and west along 12^th Street (Highway 42) from Ellis Road to the west end of the Cherry Lake Subdivision, or about one mile. The water main will be bored under 12^th Street using trenchless construction. At the other intersections in the project, pavement will be removed and replaced to install the water main.

Bidding of the project is scheduled for mid February, and an Open House will be scheduled after the contract is awarded. Details will be communicated on this webpage and via mail to residents in the construction zone. 

Commuter Route Information

Traffic control will be split into three phases for the project, starting with Phases A&B on Ellis Road.

During Phase A:

• Northbound traffic traveling in the outside northbound lane on Ellis Road will be required to merge into the inside northbound lane sooner than usual for the contractor to install a temporary asphalt lane on the east side of Ellis Road.

During Phase B:

• Windmill Ridge Street access to Ellis Road will be closed for 3 – 4 weeks; traffic will be directed to use 22^nd Street.
• Traffic on Ellis Road will be reduced to two lanes of head-to-head traffic on the east side of the median.
• Stoney Creek Road intersection will be open as a two-way stop with no left turns; traffic will be encouraged to use 22^nd Street.

During Phase C:

• Lakeside Drive intersection will be closed for 1 – 2 weeks.
• Traffic entering and exiting the Cherry Lake Subdivision from 12^th Street (Hwy 42) will be required to use Cherry Lake Avenue.

During Phase D:

• Cherry Lake Avenue intersection will be closed for 1 – 2 weeks.
• Traffic entering and exiting the Cherry Lake Subdivision from 12^th Street (Hwy 42) will be required to use Lakeside Drive.
