Water main work will close northbound lane of SW Terwilliger Blvd., north of SW Capitol Hwy. this weekend
A contractor for the Portland Water Bureau will work this weekend on the traffic island at SW Terwilliger Boulevard and SW Capitol Highway. The work will begin on Friday, November 21 at 6:30 p.m. and run through the weekend, during both daylight and nighttime hours until it is completed.

The northbound lane will be closed for approximately 200 feet and flaggers will direct traffic around the construction zone. The night work is necessary in order to maintain two lane access to Oregon Health Science University hospital during weekdays as required by the Portland Bureau of Transportation.

Motorists and bicyclists are urged to use alternate routes, remember to drive slowly, and exercise caution when traveling in the construction area.

Traffic impacts in SW Hillsdale neighborhood next week

The SW Carolina Pump Mains- Phase 2 water main installation project will impact traffic on several streets in the Southwest Hills neighborhood next week.  

  • Approximately 300 feet of the left westbound lane of SW Capitol Highway, just east of the intersection of SW Capitol Highway and SW Terwilliger Boulevard, will be closed beginning Monday, October 13, from 7:00 a.m. to 3:00 p.m. The closure is scheduled to end on Friday October 17, at 3:00 p.m. Pedestrians using the alternate walking trail who wish to cross SW Capitol Highway going south will be guided to the crosswalk by a flagger.

Road Restoration on  SW Terwilliger Blvd. in Progress

A contractor for the Water Bureau has begun the road restoration work on SW Terwilliger Blvd. this week. The work will last the next 2-3 weeks, but is dependent on dry weather. This is the final stage to the work on SW Terwilliger Blvd.

This work requires that steel plates be placed over the open trenches while the temporary asphalt is removed and permanent paving is installed. The contractor will make every effort to stabilize the plates to reduce the noise caused by vehicle traffic.

 

 

 

George Himes Park Trail Detour

Construction will occur on approximately 350 feet of the paved trail in Greorge Himes Park between SW Terwilliger Place and SW Capitol Highway beginning in late August, and will last three to four weeks.  Trail users will be detoured onto the gravel trail just 15 feet east of the paved trail.

Project Background

Tapani, Inc. will install 3,400 feet of new 24-inch diameter pipe from the intersection of SW Burlingame Avenue and SW Chestnut Street, north along SW Burlingame Avenue, then turn east on SW Burlingame Terrace down to SW Terwilliger Boulevard. Once on SW Terwilliger Boulevard, the construction will continue north until the traffic island at SW Capitol Highway where new underground vaults will be installed by Portland Water Bureau crews.

Click to open map While fairly straightforward, the project is expected to be challenging due to its neighborhood impacts. A deep five-foot wide pipe trench will need to be dug through narrow, 10 to 12 foot wide residential streets. Once the project moves onto SW Terwilliger Boulevard, traffic impacts are expected to be significant since this is a major thoroughfare through Southwest Hills communities. One lane going each direction will be closed during this phase of the project.

No travel lanes will be closed on SW Capitol Highway and SW Terwiliger Boulevard during:

  • Run Like Hell- October
  • Toy N Joy Ride- December

On some streets, the work may require a temporary street closure to regular traffic during construction hours, typically from 7:00 am to 6:00 pm, Monday through Friday.  Barricades for “Local Access Only” will be stationed. There will be some temporary inconvenience to street residents, such as equipment noise, dust and no street parking.  Every effort will be made to accommodate residents’ needs during this construction.

Under normal conditions, about 200 feet of pipe can be laid in a single day. Once the pipe work is completed, a crew will return to place permanent asphalt over the trench. Individual properties are not connected to this supply pipeline.  There will be no planned interruption of water service to the area.

One short section of the project near SW Terwilliger Boulevard-- inside George Himes Park-- will involve boring under the pedestrian pathway up to SW Capitol Highway. The work will require a brief detour of the path. A safe detour route for pedestrians and bicyclists to get around this work zone has been identified.

A construction schedule will be posted as soon as it has been determined. This webpage will be updated at least monthly. Postcard updates will also be mailed on a regular basis.
