(July 31, 2025) The Portland Bureau of Transportation (PBOT) will conduct expansion joint repairs and replacements on the NE 28th Avenue overpass over I-84 from Monday, Aug. 4 to Friday, Aug. 8 from 7 a.m. to 5 p.m. each day.
During construction, the bridge will be closed to all motor vehicles. Steel plates will be installed at the end of each workday to allow access for motorists outside of work hours. Sidewalks will remain open for pedestrians and bicyclists during repairs.
The traveling public is advised to expect delays, travel cautiously, and use alternate routes if possible.
As always, please keep our crews safe by following all traffic control signs and flaggers while travelling through or near work zones.
While some of Portland’s most iconic bridges, such as those over the Willamette River, are owned and operated by other agencies (Multnomah County, ODOT, Trimet, or railroads), PBOT owns and maintains 159 bridges citywide. Almost half of these bridges are over 50 years old, aging without enough funding to replace them. PBOT currently has $700,000 of capital funding available per year for bridge maintenance, while the average cost of bridge replacement is $15 million. The approximate cost to bring all of our bridges into State of Good Repair (best practice for asset maintenance) is $587 million.
As bridges age, they are more prone to damage and to becoming weight restricted. Weight restrictions mean that large trucks and sometimes emergency vehicles cannot use them. This adversely affects the movement of goods, emergency response times, and community resilience. The vast majority of our bridges are also not seismically resilient and would be subject to failure during an earthquake. Moving forward, as we replace bridges, we are constructing them to be seismically resilient.
