Interstate 5 (Pacific Highway)

February 28 - March 7, 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 ReplacementBeginning in February/March*, 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) will be replaced. 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.

T​raffic Impacts: Expect shoulder and single lane closures on I-5 in both directions, Monday through Friday nights from 10 p.m. to 5 a.m. to construct site access for drilling work between Southwest Corbett Avenue and North Lombard Street.​

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 until approximately March 2015. 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 and will continue for about six weeks.

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: The two westbound lanes of Southwest Lower Boones Ferry Road will be closed the night of Thursday, March 5 starting at 8 p.m. to allow concrete to be delivered for pouring the new bridge deck.
