Motorists and cyclists, take note: a crucial connection point in Portland's traffic system will soon be off-limits for a spell. The SW Capitol Highway ramp to SW Barbur Boulevard will shut down on July 15 for a necessary round of reparations, slated to last approximately six weeks. This decision comes after the Portland Bureau of Transportation observed distress on the deck of the 66-year-old bridge that also saw a sudden closure in 2018 for emergency fixes.
According to a public advisory from the City of Portland, the concern this time around is fundamentally the same—rising distress in the deck that must be addressed, lest a more dire situation unfolds. Back in 2018, concrete from this very ramp dropped onto SW Barbur Boulevard below, exposing the aging infrastructure's vulnerabilities. The upcoming work involves a full-depth concrete repair to ensure the bridge's usability and safety. During this repair period, daytime single-lane closures were necessitated for public protection.
Eastbound traffic on SW Capitol Highway will detour via either SW Terwilliger or SW Bertha boulevards to reach SW Barbur Boulevard northbound, while westbound journeys from SW Barbur to SW Capitol remain unaffected. Intermittent traffic snarls are predicted, and public transit users are advised to check with TriMet for route updates and potential delays.
The bridge, a steel-and-concrete girder structure of 554 feet, is under the jurisdiction of the Portland Bureau of Transportation. Regular assessments courtesy of the Oregon Department of Transportation, adhering to National Bridge Inspection Standards, occur biennially—and this particular bridge is due for its next examination in September. Road users are urged to heed detour signs, follow the instructions of flaggers, and opt for alternate routes if at all possible.
Lastly, nature holds a wild card in this complex urban interlude, as the entire project's timeline rests upon amenable weather conditions. Thus, commuters are signaled to keep a lookout for any changes to the repair schedule.
