Traffic Alert: Signal work at east end of Sellwood Bridge during non-peak hours on Feb. 9

Project Notice - February 8, 2017

On Thursday, February 9 from 9 am until some time before the afternoon commute, a contractor will be working on the traffic signal at SE 6th Ave. and SE Tacoma St. at the east end of the Sellwood Bridge. The westbound left turn signal on Tacoma St. will be turned off for several hours during the work. Drivers can turn left from Tacoma at SE 7th Ave. and cross streets to the east during the work. The eastbound left turn from Tacoma St. to 6th Ave. will also be closed for several hours during the work, so eastbound drivers will need to turn left at a street to the east.

New Sellwood structure stands out in Bridgetown

By Kent Hohlfeld, Architecture and Engineering - January 20, 2017

One of the most expensive and intensive transportation projects in Portland in recent memory was honored by the American Council of Engineering Companies’ Oregon chapter on Wednesday. The organization named the Sellwood Bridge replacement, as submitted by T.Y. Lin International Group, its project of the year for 2016 during its annual awards ceremony.

“It is a great honor anytime you spend all the years we have spent on this,” said David Goodyear, chief bridge engineer for T.Y. Lin International. “It’s what we work for: a happy client and recognition for the works we do.”

T.Y. Lin International served as the lead architect for the nearly $320 million project – the costliest for Multnomah County at the time it moved forward. The firm also served as the lead structural engineer responsible for bridge design alternatives, and as the engineer of record for the replacement bridge. In addition, T.Y. Lin International oversaw bridge, roadway, architectural, electrical, environmental permitting, geotechnical and landslide stabilization design teams. The firm also led the quality control program for the bridge, which opened to traffic in February 2016.

Sellwood Bridge traffic alert: Work will divert pedestrians/bicyclists

Project Notice - January 23, 2017

Starting Monday, January 23, bicyclists and pedestrians crossing the Sellwood Bridge will be re-routed a short distance around a piece of construction equipment that will be stationed on one of the bridge sidewalks. Crews will use the snooper truck to install architectural light fixtures below the bridge deck. The daytime work is expected to last through January 27, possibly longer. Traffic cones and signs will direct bicyclists and pedestrians safely around the equipment. The work will impact only one sidewalk at a time. The equipment will be removed on nights and weekends.

Field Work Notice - January 19, 2017

As construction wraps up, the contractor is working on clean-up tasks throughout the project area.  The field work notices describe major work items rather than these clean-up tasks. If no significant work is scheduled, we will not send out a field work notice each week.


Hwy. 43: The slope under the westernmost span of the bridge is being restored as the work zone closes. The permanent concrete barrier will be installed on the outside of the northbound lane under the bridge next week.

Multiuse Path Bridge:  A protective barrier needs to be installed at the bottom of the fence on this bridge that will carry bicyclists and pedestrians from the regional trail under the main bridge to reach its south sidewalk.  County staff expect to install the barrier later this month after parts arrive.

Trolley Corridor: Concrete was poured for curbs this week where the trolley tracks cross the Macadam Bay driveway. On Thursday, Jan. 19, the trolley crossings at Macadam Bay and the regional trail north of the bridge will be paved, weather permitting. Raised warning domes for visually impaired pedestrians will be installed where the trail crosses the tracks near the bridge.
