Interstate 5 (Pacific Highway)

April 25 - May 2, 2015*


*Schedules are subject to change due to weather and site conditions.

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

Project DescriptionThe 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 begin replacing many of the green highway signs on I-5 from Southwest Corbett Avenue to North Lombard Street and on both decks of the Fremont Bridge (I-405). Existing signs will be updated to meet federal standards; new signs will feature more reflective materials and a less cluttered design, making them easier to read. 
    • Paving: Starting this spring/summer*, about seven miles of I-5 between Southwest Capitol Highway and the Marquam Bridge will be repaved. 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 single and double lane, shoulder, and ramp closures on I-5 Monday night through Saturday morning, from 8 p.m. to 6 a.m. for site preparation, survey and drilling work for the new signs.

    • Drilling on I-5 southbound milepost 301.13 (just south of the I-84 to I-5 on-ramp) will require closure of the right lane and shoulder on I-5 and right lane of I-84 on-ramp from 10 p.m. to 6 a.m. The I-84 on-ramp will remain open. 
    • Sign surveying on I-5 northbound between mileposts 302.29 and 304.93 (approximately between the Rose Quarter and North Rosa Parks Way) which will require single and double lane closures between 8 p.m. and 6 a.m. Monday night through Saturday morning.
    • Sign surveying on I-5 southbound between mileposts 305.44 and 302.35 (approximately between I-405 and North Lombard Street) which will require single and double lane closures between 8 p.m. and 6 a.m. Monday night through Saturday morning.
    • Daytime shoulder closures for site work on I-5 northbound and southbound between the Marquam Bridge and North Lombard Street.

Interstate 5 Bi-State Travel Time Signage Project

Project Description: This project is installing five new travel time signs in the Portland-metro region, in coordination with Washington Department of Transportation. Construction is expected to be completed by the end of April 2015.

Traffic Impacts: The right lane on I-5 at Southwest Norwood Road (Tualatin) and Southeast Sunnyside Road (Clackamas) will be closed for nighttime sign installation on Friday and Saturday nights, April 24 and 25. Travel lane closures will only be at sign installation locations starting at 10 p.m. and completed by 10 a.m. the following morning.

Travelers should expect periodic shoulder closures and additional work on I-5 at Southwest Norwood Road (Tualatin),Southwest Gaines Street, Interstate Bridge, Northeast Airport Way (Portland), and Southeast Sunnyside Road (Clackamas) during April 2015.

Interstate 5 at Southwest Hood Avenue Bridge

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 ImpactsThe I-5 bridge work over Southwest Hood Avenue in South Waterfront requires a 24-hour single lane closure on Southwest Hood Avenue under the I-5 bridge with construction completed in May 2015 (schedule is weather and site dependent and subject to change). Due to this lane closure, road users are not permitted to continue straight on Southwest Bancroft Street from Southwest Hood Avenue. All traffic on Southwest Hood Avenue will be required to either turn right or left on Southwest Macadam Avenue. A fully signed detour is in place directing road users back to Southwest Bancroft Street via Southwest Macadam Avenue, Southwest Curry Street and Southwest Moody Avenue.

Interstate 5 at Southwest Barbur and Southwest 26th - Stormwater Management

Project Description: Environmental Services and the Oregon Department of Transportation are constructing a series of terraced stormwater rain gardens and pipes to collect sediments and pollutants before the water enters Tryon Creek. The work started on February 2, 2015.

T​raffic Impacts: The right lane and shoulder of northbound I-5 will be closed Monday through Friday from 8 p.m. to 5:30 a.m. and on Sundays from 9:30 a.m. until 7:30 p.m. This schedule is subject to change due to conditions underground, weather, traffic impacts, subcontractor schedules and availability of materials.​

Interstate 5 at Southwest Lower Boones Ferry Road

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 periodic nighttime lane closures on Lower Boones Ferry Road in both directions Monday to Friday from 8 p.m. to 6 a.m. Flaggers will be directing traffic.
