104th Avenue Waterline Replacement Project

Project Update - Nov. 21

The contractor will continue to work on extending connections from the new main to existing mains at Wolff Street and Sheridan Boulevard. The final connection at Sheridan Boulevard is scheduled to occur in mid-December. The new mains will go through water quality and pressure testing before they are placed into service. Final paving may be scheduled for next spring depending on the weather. The connections to existing mains will require temporary traffic control shifts with detours and lane closures. Safety of the public and of the contractor crews is of the utmost importance and abiding by all construction-related signs is greatly appreciated.

Upcoming - No Date Confirmed

Expect major delays at the 104th Avenue and Sheridan Boulevard intersection as aging waterlines are replaced. The work is expected to last several days with multiple lane closures in all directions (north and southbound Sheridan Boulevard, and east and westbound 104th Avenue). ALTERNATE ROUTES ARE STRONGLY ADVISED. Multiple lane closures will be in place 24/7. Work will be conducted between 7 a.m. and 5 p.m. Thank you for your patience as we replace aging waterlines so that we can continue to provide you with safe and healthy drinking water.

Project Details

For the past several years, the City of Westminster has been coordinating the replacement of aging infrastructure in 104th Avenue. To date construction improvements have included water valve replacement and work by Xcel Energy.  

The next improvements involve construction of a new water transmission main to replace aging water systems that have reach the end of their useful life. The new water transmission main will be installed in 104th Avenue between Sheridan Boulevard and Hooker Street (see map).  

As part of the project, resurfacing of 104th Avenue between Sheridan Boulevard and Federal Boulevard will also be completed. The new water main will serve a large area of Westminster. Connections to the new water main will be sequenced to minimize service interruptions as much as possible.

Project Timeline

Construction is scheduled to start in March and will extend through the fall. 

Project Hours

Normal work hours will be Monday through Friday beginning no earlier than 7 a.m. and ending by 5 p.m.

Special circumstances may arise requiring extended work hours and in some locations nighttime and weekend construction will be necessary to avoid times of higher traffic volume.

Project Safety

During working hours, construction equipment will be in operation and some materials may be stockpiled close to the work area. The contractor, Northern Colorado Constructors, Inc., will maintain traffic control during construction and will maintain access to side streets and parking lots as much as possible. However, temporary lane closures, sidewalk closures and detours may occur.  

Safety of the pedestrian, biking, motoring public and of the contractor crews is of the utmost importance. Assistance in abiding by all construction related signs is greatly appreciated. Should you observe an emergency situation please call 911.
