Riverview Force Main Replacement Project

Environmental Services is planning a project on Highway 43 to replace an aging sewer main that carries wastewater from the Riverview Pump Station. The project will replace roughly 3,000 feet of failing sewer pipe along Highway 43 from the Riverview Pump Station south to SW Riverwood Road (see map). The pipe has experienced several failures in recent years, and this project will install a new pipe and reduce the potential for future leaks or breaks.

Project Schedule and Night Work

Construction begins June 7 and will take between four and six months to complete. Work will take place both during the day and night. Daytime work hours will be 9:00 a.m. – 3:00 p.m. and nighttime work hours will be 8:00 p.m. – 5:00 a.m. Monday through Friday, and on the occasional weekend. Crews will not be working during the morning and evening commutes. The project team will coordinate the traffic controls with other sewer and road projects in the area to minimize impacts on residents and commuters.

During work hours on Highway 43, the contractor will keep one travel lane open in each direction. There may be several nights when only one lane is open and flaggers will direct traffic through the work area. When crews cross the highway to connect the new pipe to the manhole on SW Riverwood Road, only one lane will be open and flaggers will be on site to direct traffic. Traffic onto Riverwood Road will be temporarily detoured, 24 hours per day, for up to one week. Travelers through the area should expect some delays during construction.

You may see construction materials stored on or near the road. The contractor will maintain access to driveways and residential streets at all times.

What to Expect During Construction

  • Work hours are 9:00 a.m. to 3:00 p.m. and 8:00 p.m. to 5:00 a.m. Monday through Friday. There will be occasional weekend work.
  • Construction will create noise, vibration and dust and may disrupt normal neighborhood activity.
  • Traffic control signs will be set up. The contractor maintains local access, but expect delays.
  • On-street parking in or near the work area may be limited during construction hours.
  • Equipment and materials are stored on nearby streets overnight.
  • There may be periods of inactivity between construction phases.
  • A city inspector is on-site during work hours and may be able to assist you with construction concerns. Inspectors typically wear a City of Portland safety vest and hard hat.
  • Please stay clear of all construction activities and keep children and pets clear of all construction activities.
  • Some tree trimming of branches that overhang the right-of-way will be conducted by professional arborists. Only branches that limit access of the construction teams will be trimmed.
