I-405 Repaving Project

This summer, ODOT will pave I-405 from the Marquam Bridge to the Fremont Bridge. The pavement is severely rutted and will be filled and paved to improve highway safety. The project will also install new lighting and signs along the I-405 corridor. Work is scheduled to be completed by the end of 2009.

Night and Weekend Closures

I-405 is one of the busiest sections of freeway in the Portland metro area. The high volume of traffic requires that lanes remain open during weekday daytime hours. Therefore the following weekend and weeknight closures will be utilized:

I-405 Paving

• Four weekend full single-direction (north or south) closures will be required for paving work. Full roadway closures are limited to two weekends per direction. It is anticipated that these closures will take place sometime in July, August, or September. Work is weather dependant.
• Closures are prohibited from taking place during the Rose Festival Grand Floral Parade, Bridge Pedal, Hood to Coast, and Race for the Cure.
• Nighttime lane closures also will be used throughout the duration of the project.

Ramp Work

• Ramps will be closed during the full single-direction closures.
• Single lane closures may occur on the ramps at night throughout the duration of the project.

Ramp Tunnel Lighting

• Three ramp tunnels will receive new permanent lighting.
• One tunnel at a time can be closed from 7:30 pm - 5:30 am for light installation.
• It is anticipated that each tunnel will take one week of nighttime closures.

Sign Replacement

• Sign replacement on two cantilever sign structures will require single lane closures on local streets under the structure.
• Other sign replacement wok on I-405 may require single-lane nighttime closures.

Detours

I-5 is the main detour route for through traffic during the full single-direction closures of I-405. Specific detours for trips beginning and ending in the project area, ramp work and interchange closures will be available in the next few weeks and posted on the project website.
