B Avenue construction - pipe installation progressing through the business district

Pipeline construction is moving down B Avenue at a brisk pace and crews are currently working between 2nd and State Streets. Work hours are 7 a.m. to 6 p.m., Monday through Friday. Rolling block closures are in place while crews are working in the area. Please watch for signage directing you safely around the closure. The area where the pipe is installed will be temporarily paved as the crew progresses, however, steel plates may be present in the roadway. Please drive with caution when traveling in the area.

Final paving will occur after the pipeline has been installed and tested, likely in June. To minimize impacts, crews may pave the business district at night and the residential area during the day, and expect to resurface two to three blocks at time.

The Partnership is committed to keeping B Avenue “Open for Business” during construction and to respond promptly to business and neighbor concerns. Pedestrian access to all businesses will be provided during construction and “Open for Business” signage will be placed on sidewalks and barricades in the work zone.

State Street nighttime construction - set to begin this summer

Pipeline construction is expected to begin this summer on State Street, from B Avenue, south under the railroad tracks. From here, the pipeline will be installed along a portion of Foothills Road, through the Oswego Village Shopping Center, the Old Town neighborhood, George Rogers Park and McVey Avenue.

To minimize traffic and business impacts, most work on State Street will occur at night. In most areas, one lane of traffic will be open in each direction, with flaggers guiding traffic through. All lanes will be open to traffic during the day.

Exploratory digging - crews working off Foothills Road, near State Street

Next week, crews expect to complete the last of their exploratory digging in preparation for pipeline installation. They will be working in the alleyway behind the businesses just off State Street and Foothills Road. Last week, crews also removed a few trees, which were permitted for removal, along the pipeline alignment near the intersection of Oswego Pointe Drive and Foothills Road.

McVey Avenue pipe bridge - preparations begin next week

Next week, crews will begin clearing the area near Oswego Creek and installing temporary fencing and erosion controls for the upcoming construction of the pipe bridge, off McVey Avenue. Near the end of May, crews will take the next step by beginning to form and pour the bridge’s footings. This work will be done during the day between 7 a.m. and 6 p.m., Monday – Friday.

Highway 43 nighttime construction - pipeline testing continues

Over the next month, small crews will continue working along the pipeline alignment on Highway 43, between Laurel Street and Mapleton Drive. Work includes making pipe connections, along with filling, hydro testing, disinfecting and chlorinating the pipeline. Once this work is complete, final paving of the lane where the pipe was installed will occur. This is expected to begin sometime in June.

Crews have replaced concrete panels on Highway 43 in West Linn, between Mapleton Drive and Cedar Oak Drive and the concrete has cured. This week, crews are repaving over the concrete panels—neighbors may notice an increase in construction noise during this work.

Nighttime work hours on Highway 43 are 8 p.m. – 5 a.m., Sunday through Thursday. During construction, one lane will be open at a time in most areas, with flaggers guiding traffic in each direction.
