Environmental Services is working on a project to replace an aging sewer main on Highway 43 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.
Developments of Note
- Saw cutting has been postponed until Monday night, July 13 due to underground conditions.
- Daytime work hours to locate utilities are 7:00 a.m. to 4:00 p.m. until approximately July 10. After utilities are located, daytime work hours will return to 9:00 a.m. until 3:00 p.m.
- One lane of Highway 43 will be open intermittently. Flaggers will direct alternating traffic from north of SW Radcliffe Road to south of SW Carey Lane.
Construction began June 9 and will take about six months to complete. Work progresses from north to south in stages. Work will take place both during the day and night. Daytime work hours are 7:00 a.m. to 4:00 p.m. until pre-construction potholing is complete. After July 6th, daytime work hours return to 9:00 a.m. to 3:00 p.m. weekdays. Nighttime work hours will be 8:00 p.m. – 5:00 a.m. Sunday through Thursday.
June – August:
- Daytime work including potholing and locating utilities.
- Staging equipment near the work zone
- Night work including saw cutting, trench excavation and disposal of pavement (beginning July 6th)
- Install pipe
- There will be no work Friday, July 3; nor Sunday July 5 in observance of the Independence Day holiday.
Please be aware that this schedule is subject to change due to a variety of factors including underground conditions, weather, subcontractor schedules, and availability of materials.
Given the heavy volume of traffic Highway 43 conveys, work hours have been arranged so that construction impacts are minimal 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 night work, traffic exiting the west side of Highway 43 from private driveways and streets without signal lights will be “Right Turn Only.”
- Please plan accordingly. Motorists should expect delays.
- There will be several days and nights when only one lane is open and flaggers will direct alternating 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. Notification will be sent once this is scheduled.
- 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.
What to Expect During Construction
- Nighttime work hours 8:00 p.m. to 5:00 a.m. Sunday through Thursday.
- Daytime work hours are 7:00 a.m. to 4:00 p.m. Monday Through Friday during pre-construction potholing. Hours will return to 9:00 a.m. to 3:00 p.m. on weekdays after July 10.
- Construction will create noise, vibration and dust and may disrupt normal neighborhood activity.
- You may see construction materials stored on or near the road. The contractor will maintain access to driveways and residential streets at all times
- 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 will 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.
- Safety is a top priority. 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 will be trimmed.
Night Work and Noise
Because the project is extensive and Highway 43 has high traffic volume, the Oregon Department of Transportation (ODOT) has directed Environmental Services to schedule both daytime and nighttime construction. Typical overnight construction hours will be 9:00 p.m. to 5:00 a.m. During pre-construction daytime work hours will be 7:00 a.m. to 4:00 p.m. After July 10, daytime construction will take place from 9:00 a.m. to 3:00 p.m. This schedule is designed to minimize impacts on commuters and neighbors. Environmental Services is coordinating construction with other projects, including the Sellwood Bridge project.
Work will be loud, but the contractor will take steps to minimize construction noise. If you have questions or concerns during night work, you can call the City of Portland onsite hotline at 503-823-8353. If you have questions or concerns about the project during regular business hours, please contact Ashley Tjaden at 503-823-5281 or firstname.lastname@example.org.
The contractor will use open trench construction. Crews may also use utility trucks, backhoe, and lights during night work hours. You can find more information about sewer construction methods at www.portlandoregon.gov/bes/methods.
