Upper Drive and Iron Mtn. Blvd. paving and striping

Residents located along the pipeline alignment on Upper Drive and Iron Mtn. Blvd. will receive a door hanger 48 hours in advance, notifying them of the dates for paving on their street. On narrow roads, such as Upper Drive, there will be periods where roads are temporarily closed to all traffic, so the new pavement can dry. On Iron Mtn. Blvd., some areas will receive full width paving and some will receive paving on one lane only. During Iron Mtn. paving, one lane will remain open at all times, with flaggers. However, it may be more convenient to find an alternate route to avoid delay. Roadway striping (center lines, fog lines, speed bumps, pathways, etc.) will occur after paving.

A reminder to pedestrians, runners and cyclists: make eye-contact with a crewmember and signal your presence before proceeding along the Iron Mtn. pathway, if grinding or paving is nearby.

To view the latest road closures and construction activity, please visit the work underway map and zoom in to the location you are interested in.

B Ave. storm drain construction—1st Street to 2nd Street

Construction of the new stormwater pipeline on B Ave, between 1st and 2nd is making good progress.

New information:

  • Mid-week, the contractor hit hard rock in the bottom 1-2 feet of the trench. A rock hammer will need to be used intermittently to remove the rock. Neighbors will hear more noise from the rock hammer than the typical excavation that has been occurring.
  • 24-hour closures between 1st and 5th Streets. To improve safety for drivers and cyclists and to speed construction along, the contractor will be keeping each one-block work zone on B Ave between 1st and 5th Streets closed to through traffic after construction hours. Thank you for your patience as this work progresses.
  • Next week, crews will progress to the block between 2nd and 3rd Streets.

Construction hours are to 7 a.m. to 6 p.m., Monday to Friday. Pedestrian access to all businesses will be provided within the one block work area, but no on-street parking will be available in the closed area. Parking is available on side streets and outside the work zone on B Ave, as well as in City parking lots downtown.

Laurel St. pipeline construction completes three blocks! Erickson pipe work begins Monday.

Construction crews have now progressed three blocks on Laurel St and are now between O’Brien and Gans Streets. During construction, Laurel will be closed to through traffic between Hwy. 43 and Hallinan St. from 7 a.m.-6 p.m., Monday to Friday.

Northwest Natural Gas will be relocating a gas line in the Laurel Narrows after pipe installation is complete on Laurel between Hwy 43 and Hallinan. This is to make way for the large water pipeline to be constructed in the Narrows later in October.

A second crew is expected to begin laying pipe in Erickson Street next week. Erickson Street will be closed to through traffic between McVey and Laurel Streets. Parking will not be available on Erickson within the work zone and work is expected to take about four weeks. Services such as mail delivery, garbage and recycling collection and other deliveries will continue during construction.

Durham Street cultural resource work starts next week

Starting next Tuesday, September 16 , crews will begin excavation of five, 7 foot by 30 foot work areas along Durham Street between Leonard and Ladd Streets. The purpose of this work is to further explore potential cultural resources in the area prior to pipeline construction that will begin in early 2015.

Work will take about five weeks. After work hours, the work area will be covered with a steel plate, with temporary paving to follow. During work hours, there will be single-lane closures with flaggers. Up to 20 people will be working on site at any one time.

Hwy. 43 pipeline construction (night work) – delayed to October

Crew and steel pipe availability is resulting in Hwy 43 work being delayed to October. Work will progress south towards West Linn. All work on Hwy. 43 will be conducted at night between 8 p.m.-5 a.m. In most areas on Hwy. 43, two-way traffic will be maintained during construction. All lanes of traffic will be open during the day. By November, a second crew will begin pipeline construction in West Linn at Mapleton Drive on Hwy 43 and will work north to Lazy River Drive.

Thank you for your patience as construction progresses.
