What is the Agler Road NCHP Project?
To comply with federal requirements, we are replacing gas lines on Agler Road between Gatewood Road and Big Walnut Creek. There are no scheduled interruptions to your Columbia Gas service as a result of the construction. As most of the work is to be conducted within the road right-of-way, construction will affect the flow of traffic for the duration of the project as we progress through various phases of the replacement. We ask that motorists be patient and respectful of all work zone directives during this time and obey all posted signage and instructions throughout construction.Expected start date: February 2027
Expected end date: December 2027
Distance: 2.33 miles of pipe
