Interstate 5 - Southwest Capitol Highway to North Lombard Street - Paving and Signs

Project Description: The project will take place on Interstate 5 from Southwest Capitol Highway to North Lombard Street and will include:

    • Sign Replacement: Work is under way to replace many I-5 green highway signs from Southwest Corbett Avenue to North Lombard Street and on both decks of the Fremont Bridge (I-405) to meet federal standards; new signs will feature more reflective materials and a less cluttered design, making them easier to read.
    • Paving: Work is under way to repave approximately seven miles of I-5 between Southwest Capitol Highway and the Marquam Bridge. The pavement, last replaced in 2004, is deteriorating and needs to be repaired. Transitions to on- and off-ramps will also be repaved and improvements will be made to several bridges.​ 

*Construction is scheduled to be complete by the end of 2015, but work is weather dependent and dates are subject to change.

Traffic Impacts: Expect nighttime construction work for sign replacement, structure installation and paving. ODOT is partnering with law enforcement for extra presence in the construction zone.

Interstate 5 at Oregon Highway 99W - Southwest Barbur Boulevard

Project Description: Construction is underway on a seismic retrofit project for five bridges along the Interstate 5 corridor between Portland’s South Waterfront district and the Tualatin River. Retrofitting the state’s older bridges to meet modern seismic specifications will help ensure I-5 would not be immobilized in the event Oregon experiences a powerful earthquake.

Traffic Impacts: Expect nighttime single left lane closures in the south and northbound directions, Monday through Thursday as crews continue working on the center column.
