Center span of Portland's new Sellwood Bridge linked

By Randy L. Rasmussen,The Oregonian - March 31, 2015

Workers have nearly spanned the Willamette River with steel arches for Portland's new Sellwood Bridge. On Tuesday, sections of one of the center arches were joined when the "keystone" piece was lifted into place and secured with thousands of bolts.

Mike Pullen, spokesman for Multnomah County's bridge project, said that he expected by end-of-day Tuesday that both spans of the center would be completed.

TRAFFIC ALERTS

April 17 – 20 Bridge Closure: The contractor plans to close the bridge to all traffic from 7 pm on Friday, April 17 until as late as 6 am on Monday, April 20 to implement a traffic pattern change at the west end of the bridge and install deck girders for the east approach.  When the bridge reopens, traffic will use the new west approach which will transition onto the detour bridge. This will allow construction of the ramp from the bridge to northbound Hwy. 43. Highway traffic will not be impacted by the bridge closure.

Hwy. 43 traffic impacts:

  • Lane closures are planned from 9 am to 4 pm next week in the southbound outside lane north and south of the bridge during finish work on retaining walls and installation of gutters behind the walls.
  • The outside northbound lane will be closed next week from 7 am to 4 pm between the bridge and Freeman Motors during work to connect the new 36-inch waterline.

Concrete Repairs Explained

Construction Update - March 24, 2015

Related articles

Recent news stories have reported on concrete repairs that are being made to a column on one of the Sellwood Bridge river piers. Several stories reported that chunks of concrete had fallen from the column, which is not correct. The voids in the column are areas where the contractor intentionally removed concrete that did not consolidate (mix well) during the pour.  After the bad concrete is removed, the void is filled with a grout that is stronger and more durable than the original concrete.  The repair is the contractor's responsibility and does not affect the project's cost, schedule or quality. After the column surface is finished and stained, the repair will not be visible. Similar concrete repairs have been performed on other bridge projects around the state, following a state specification. The county and the contractor have taken steps to improve the quality of concrete pours on the project.
