PORTLAND — The planned July 19 closure of the U.S. 30 ramp to southbound Interstate 405 has been postponed while crews carry out additional assessments needed before taking on the work.

The ramp had been scheduled to close for 11 days starting July 19. The work was a major part of the I-405 Ramps Project, which, when complete, will repair or replace 42 bridge joints along I-405.

The postponement will ease traffic concerns that would have been created by two simultaneous closures: Multnomah County’s 11-week closure starting later in July of Cornelius Pass Road between Germantown Road and U.S. 30 and ODOT’s I-405 Ramps Project . The Cornelius Pass closure is expected to force additional traffic onto U.S. 30 and I-405 which would have become more congested by closure of the on-ramp.

We have not yet rescheduled the U.S. 30 ramp to southbound I-405 closure. Travelers should expect nighttime closures of the ramp later this summer.

The delay of this ramp closure will have no impact on the other work planned in the I-405 Ramps Project.
