Field Work and Construction Updates

Updated January 27, 2017: With major construction work now complete, there will no longer be a weekly Field Work Notice. Notices will be posted in 2017 if important field work is scheduled.

In-Water Work for January; Holiday Hours

Field Work Update - December 30, 2011

In-water work to place piles for the detour bridge continues. Two cranes will be operating to perform this work. In-water work will continue through the end of January.

Work Hours

The contractor will not work on December 31 and January 1. Normal work hours during the winter in-water work period are 7 a.m. to 6 p.m. Monday through Saturday and 9 a.m. to 6 p.m. on Sunday. Weekend work may be less common after the in-water work is completed.

Land based work on the eastside is expected to begin in late February or March.


In-Water Work Begins; Holiday Work Hours

Field Work Update - December 23, 2011

In-water work began the weekend of December 17 – 18, with the arrival of a barge and crane for placing piles for the detour bridge. An average of four steel piles have been placed each day to a depth of about 35 feet below the river bed. This work will continue through the end of January.

A second barge and assist crane are scheduled to arrive on December 27. For the time being, only one crane will place pile at a time. Vibratory methods, which are quieter than impact hammering, will be used to drive pile this winter.

Work Hours

The contractor will not work on December 24, 25, 26, 31 and January 1. Normal work hours during the winter in-water work period are 7 a.m. to 6 p.m. Monday through Saturday and 9 a.m. to 6 p.m. on Sunday. Weekend work will be less common after the in-water work is completed.

Land based work on the eastside is expected to begin in late February or March.


Groundbreaking; upcoming work hours

Field Work Update - December 16, 2011

Today was a big day for the Sellwood Bridge Project. About 150 people gathered with project leaders for a groundbreaking ceremony in Sellwood Riverfront Park. Earlier in the day the U.S. Coast Guard issued the last permit needed for in-water work to begin this month. Congressman Earl Blumenauer’s office was helpful in working with the Coast Guard to secure the permit.

The contractor’s river barge is scheduled to arrive onsite Saturday afternoon, December 17. During December and January, the contractor will place piles for the detour bridge river piers. Vibratory methods, which is quieter than impact hammering, will be used to drive pile this winter.

To keep the project on schedule, it’s important that the contractor places as many piles as possible during this in-water work period.

Work Hours

The contractor plans to work in the river Monday to Saturday from 7 a.m. to 6 p.m., except holidays. No work is planned on December 24, 25, 26, 31 and January 1. The City of Portland has granted permission for the contractor to work on Sundays this winter from 9 a.m. to 6 p.m. Weekend work will be less common after the in-water work is completed. 

We regret any inconvenience the weekend work presents to bridge neighbors. Land based work on the eastside is expected to begin in late February or March.


Westside and In-Water Work

Field Work Update - December 9, 2011

Westside

A construction zone will be established on the west side of the bridge starting Monday, December 12. The access road from Highway 43 to the former Staff Jennings boat store and Powers Marine Park will close permanently on December 12. The Staff Jennings property was acquired as part of the project and new parking spaces for the park will be built as part of the project.

Public access to the old Sellwood Ferry ramp next to Staff Jennings and to Powers Marine Park will close during construction.

In-Water Work

During the week of December 12, the contractor will place river safety buoys to establish a “no wake” zone within 500 feet of the construction area. River users should reduce speed in the “no wake” zone and maintain a safe distance from other boats and construction areas.

In-water work in December will include driving piles for the piers of a detour bridge that will open to traffic at the end of next summer. Depending on approvals from regulatory agencies, river pile driving could begin as early as Wednesday, December 14. The contractor will use a vibratory method to drive piles, rather than an impact pile driver.

Contractor work hours are Monday through Saturday from 7 a.m. to 5:30 p.m. during the December and January in-water work period. The contractor has requested permission to also work Sundays during this in-water work period, between 9 a.m. and 5:50 p.m. The City of Portland is considering this request. Weekend work should be less frequent after the in-water work period ends in January.


Test Pile Schedule Update

Field Work Update - September 23, 2011

There's a schedule change for the in-water work our contractor will do next week to test the pile system for the detour bridge piers. Yesterday we reported to you that mobilization in the river (on the north side of the bridge) would begin on Monday and pile placement would start on Tuesday, September 27. Due to the late arrival of some equipment, the pile placement is not expected to start until Thursday, September 29. The test pile program is still expected to be limited to weekdays and should be completed by Friday, October 7.

Core drilling on the south side of the bridge is still scheduled to begin on Monday, September 26.


Mela Building Demolition, Test Piles, Core Drilling

Field Work Update - September 22, 2011

Mela Building Demolition

The former office building under the east approach to the bridge is being demolished by a contractor. On Friday, September 23, the contractor will begin to demolish the exterior of the building. Work so far has focused on the building's interior. The contractor is expected to work for three to four more weeks to remove the structure. Work is on weekdays.

Our team reports that the bridge columns hidden by the building these past 85 years are in good condition. The piers will be revealed soon as the building comes down.

Bridge closure and test pile work

Field Work Update - September 16

Reminder: Bridge closed on Sunday, Sept. 18

The Sellwood Bridge will be closed to motor vehicles on Sunday from 7 a.m. until as late as 3 p.m. while a contractor removes small concrete samples from the bridge deck in preparation for the relocation of the bridge in 2012. The river spans will be moved 40 feet north late next spring to create a detour bridge and make space for construction of the new bridge. The bridge will be open on Sunday for bicyclists and pedestrians. Motor vehicles will need to use alternate crossings such as the Ross Island or I-205 bridges. Potholes on the bridge will be repaired and streetlight bulbs will be changed also on Sunday.

Test pile work in river in late September

The contractor plans to install and remove six test piles in the river between Monday, September 27 and Friday, October 6. The purpose of the work is to test the piles that will be installed in December to support the river columns for the detour bridge. The test piles will be installed about 40 feet north of the existing river piers. The contractor plans to set up on September 27 and begin installing piles on September 28. Work hours will be between 7:30 am and 5 pm. The contractor will vibrate the piles into the river bottom to a depth of roughly 100 feet and then use an impact driver to test their full depth. The piles will all be removed by the end of the test in early October.


Broadway and Sellwood bridges closed Sunday for field work

Multnomah County Press Release - September 14, 2011

The Broadway and Sellwood bridges will be closed on Sunday, September 18 for field work projects. The projects are not weather dependent.

The Sellwood Bridge will be closed to motor vehicles from 7 a.m. until as late as 3 p.m. During the closure a contractor will remove small concrete samples from the bridge deck in preparation for the relocation of the bridge in 2012. The river spans will be moved 40 feet north next spring to create a detour bridge and make space for construction of the new bridge. A crew will fill pot holes and work on bridge traffic lights during the closure. The bridge will remain open to bicyclists and pedestrians. Motor vehicles should use alternate crossings such as the Ross Island or Interstate 205 bridges during the closure.

Mela Building Removal

Field Work Update - September 9, 2011

Multnomah County has hired Konell Construction and Demolition of Sandy, OR, to dismantle the Mela Building, the former office building under the east end of the Sellwood Bridge at 380 SE Spokane St. The County has acquired the building, which will be removed to make room for the new bridge.

The contractor plans to mobilize on the site on Monday, September 12 for this project, which should take two months to complete. Next week's work will include putting up a perimeter fence, installing erosion control, and doing work inside the building. Interior work will happen first. Demolition of the building's exterior is expected to start at the end of September.


Slope Drilling

Field Work Update - August 26, 2011

Sample drilling will begin August 29 on the west slope above Highway 43 just north of the Sellwood Bridge (across from Staff Jennings). Crews will drill to determine the rock composition of the hillside. The drilling will take up to two weeks to complete.


Sellwood Harbor drilling now complete

Field Work Update - August 24, 2011

The drilling in the north parking lot at Sellwood Harbor condominiums has been completed. We appreciate your patience.


August river drilling now complete

Field Work Update - August 19, 2011

River Drilling: Good news! Today the team drilling for core samples in the river completed their work for August. Also, the team was able to stop work on Thursday by 5:30 pm, earlier than expected. The team may need to come back this fall to gather more samples where bridge foundations will be located.

Drilling at Sellwood Harbor: The drilling in the north parking lot at Sellwood Harbor condominiums is expected to be completed by the middle of next week.


Late Drilling August 18

Field Work Notice - August 17, 2011

The good news is that our team drilling in the river have hit bedrock at the last boring location they are working at this month. The team is collecting bore samples where the foundations will be for the new bridge and the detour bridge. However, in order to drill deeper into the bedrock and remove the full length core sample, they expect to work a long day on Thursday, August 18. There is a risk that the bore hole will collapse if left open over night. The drill team has requested permission to work until as late as 7 pm on Thursday in order to finish removing the core sample. We expect that this will complete their work in the river for August. We regret any inconvenience due to the work.


Drilling resumes August 16 at Sellwood Harbor

Field Work Updated - August 15, 2011

The drilling operator doing the work in the Sellwood Harbor north parking lot was able to obtain replacement parts earlier than expected.  Drilling is scheduled to resume in the parking lot tomorrow, Tuesday, August 16 and continue on weekdays into next week.  Work will take place between the hours of 7:30 am and 5 pm.


River, Sellwood Harbor Drilling

Field Work Update - August 11, 2011

River Drilling: Our drill team working from a barge in the Willamette River near the bridge is encountering layers of gravel below the river bed, which slows the work. In order to keep the gravel from collapsing into the bore hole, the drillers have to grout the hole with cement as they drill to keep the hole open.

The bedrock is also deeper than expected (by about 35 feet). We estimate that the river drilling should be completed by Friday, August 19.

Sellwood Harbor Drilling: The drilling operation that began in the parking lot at Sellwood Harbor condominiums this week experienced an equipment problem. The drilling will be postponed for one to two weeks while new parts are ordered for the equipment. We hope to have an update on the drilling schedule in our next update.
