Countdown To I-5 Closures

Travelers will experience the first major delays for the Interstate 84 at Interstate 5 Rehabilitation Project and the I-5 Interstate Bridge to Hassalo paving project. 

Two week closure of I-5 southbound ramp to I-84 eastbound

The ramp that connects I-5 southbound to I-84 eastbound will close 24-hours a day for two-weeks from 10 p.m. Sunday, July 8 to 5 a.m. Monday, July 23. 

During the closure, Hamilton Construction, will replace 16 bridge joints that link  the ramps, , remove the existing concrete, perform repairs to metal below the concrete surface and emplace new concrete. As the concrete cures, traffic cannot use the ramp.

I-5 southbound weekend closure

I-5 southbound will close for paving between the Fremont and the Marquam Bridges from 10 p.m. Friday, July 13 to 5 a.m. Monday July 16 and from 10 p.m. Friday, July 20 to 5 a.m. Monday, July 23.

During these closures travelers will use the Fremont Bridge and Interstate 405. 

Significant Delays Expected

Travelers should expect delays and backups on I-5 southbound that last most of the day and night and that could stretch to the Interstate Bridge during this closure. Information on options to avoid delays are available at and on an online open house. 

People heading south should consider using Interstate 205 or other southbound routes, take transit, bike, walk, consider telecommuting or working from an alternate location.
