Iron Mtn. Blvd. paving and striping

Crews expect to finish paving Iron Mtn. Blvd by Saturday, September 27 (weather permitting). There will be periods where the road is 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 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— at the interstion of 5th Street

Stormwater pipeline construction is now between 4th and 5th and work is progressing through the intersection at 5th. Crews seem to be out of the hard rock for now. Survey and sawcutting were completed this week from 5th to 8th Streets. In 2-3 weeks, expect to see some lateral and manhole work at the intersections of 8th and B and 9th and B. This is not pipeline replacement but work that will help improve local drainage.

To improve safety for drivers and cyclists and to speed construction along, the contractor will continue to keep each one-block work zone on B Ave. between 1st and 7th Streets closed to through traffic after construction hours.

Construction hours are to 7 a.m. to 6 p.m., Monday to Friday. Pedestrian access to all businesses is 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. Thank you for your patience as this work progresses.

Laurel gas line relocation work underway; Bickner St. water line and Erickson St. main line begins

Construction crews have stopped work on Laurel between Hwy 43 and Hallinan in order to install and relocate other water lines related to the project work. In Laurel between Hallinan and Dyer, NW Natural is moving a gas line to make way for the large water pipeline. This work is expected to be completed by October 3. Laurel between Hallinan and Erickson will remain closed through November as pipe installation will follow the NW Natural work.

A new, 12” water line is being installed in Bickner Street between Laurel and Ash. This line will improve water service and fire flows to this area of Hallinan neighborhood. Work hours are from 7 a.m.-6 p.m., Monday to Friday.

A second crew has begun laying pipe in Erickson Street near McVey. A rock hammer is being used to break up large boulders during excavation of the pipe trench. 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. Neighbors may experience and increase in truck traffic and noise during construction.

Durham Street cultural resource work in the second block

On September 16, crews began 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.

Neighbors along Durham will not be able to park on Durham or access Durham from their driveway when the work area is in front of their home. Parking on a side street during work hours is recommended if you need to use your vehicle.

Work will take about three more 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. Work hours are 8 a.m. – 5 p.m., Monday through Friday, however, equipment may arrive as early as 7 a.m.

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

Crew and steel pipe availability is resulting in Hwy. 43 work being delayed to early November. Work will begin at the intersection of Hwy. 43 and Laurel St, and 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.

Thank you for your patience as construction progresses.
