Heads up on a major road project that’s about to affect dispatching and routing in the Portland area.

Starting September 11, ODOT is closing I-5 southbound between I-405 and I-84 as part of the Rose Quarter Improvement Project — a repair of a 2-mile stretch of the highway to improve safety and reduce congestion. This is expected to run 5–7 weeks, into fall 2026.

WHAT TO EXPECT

I-5 Southbound Full Closure

Complete closure between I-405 and I-84, 24/7, for up to five weeks starting September 11. One lane stays open from the I-405 junction to the Broadway/Weidler exit for local access.

Local Street Closures

Sidewalk and lane closures near the Oregon Convention Center (NE Oregon Street, N Interstate Ave, NE Lloyd Blvd) for seismic upgrades and sign structure work.

I-84 Off-Ramp Closures

Occasional closures of the I-84 off-ramp to NE Holladay St near the Moda Center and the Oregon Convention Center for sign structure work.

Nighttime & Shoulder Closures

Occasional nighttime lane closures and possible shoulder closures on I-5 to construct stormwater facilities, sign structure installation, and I-5 bridge preservation.

DETOUR ROUTES

The main detour for I-5 southbound traffic is via I-405

Access to I-84 eastbound remains open

I-5 northbound stays open at the Broadway on-ramp

Why This Matters for Us

This will likely affect delivery windows and routing through the Rose Quarter / Convention Center area for the full closure period. Worth building in extra time for any deliveries that would normally route through this stretch, and considering the I-405 detour as the default alternate.
