PORTLAND, Ore. — A four-mile stretch of Interstate 5 will be closed in both directions starting Friday night in Southwest Portland for construction crews to continue work on the Southwest 26th Avenue overpass.
The closure starts at night on Friday, June 28 and ends Monday, July 1 in the morning.
Here's what to know about the closure.
What will be closed?
The I-5 closure will stretch southbound from the Southwest Terwilliger Boulevard exit ramp to the Capital Highway on-ramp. The northbound closures will go from the Southwest Barbur Boulevard exit ramp to the Terwilliger on-ramp.
To ensure that drivers do not enter the construction zone while work is going on, the following on-ramps will also be closed:
Northbound on-ramp closures
- Southwest Kruse Way
- Southwest Haines Street
- Southwest Capitol Highway
- Southwest Spring Garden Street
- OR 99W/Barbur Boulevard
Southbound on-ramp closures
- Interstate 405 on-ramp
- South Harbor Drive on-ramp
What are the detours?
The Oregon Department of Transportation (ODOT) suggests that travelers use other major Portland-area highways — such as Interstate 205, Interstate 84, Oregon Highway 217 or U.S. 26 — if planning on going through Portland.
Southwest Barbur Boulevard will be available for local traffic.
Why will I-5 be closed?
Construction crews are rebuilding the bridge deck that spans Southwest 26th Avenue in Portland. The Interstate 5 bridge over 26th Avenue was built in 1959 and has been heavily worn down over time, as it carries over 100,000 vehicles a day.
The plan for the project is to modernize the bridge by creating a smoother surface for motorists and bringing the bridge up to modern safety and seismic standards.
How long will the closure last?
Interstate 5 will be closed in both directions for 56 hours, starting Friday, June 28 at 9 p.m. and ends Monday, July 1 at 5 a.m.
