TripCheck alerts: Nightly I-205 southbound closures near Oregon City start July 31

Drivers who commute south on I-205 near Oregon City should plan ahead: TripCheck lists new overnight I-205 southbound restrictions starting Friday, July 31, 2026 (from 11 p.m. to 7 a.m.).

These alerts are labeled as planned information, and the I-205 Corridor project notes schedules can depend on conditions like weather—so check TripCheck again the morning of travel.

What’s closing (southbound, near Oregon City)

TripCheck’s I-205 alerts for the Oregon City area cover a southbound segment of I-205 between MP 8.50 and MP 9.56.

On the project side, the direction-closure details are tied to Abernethy Bridge work with southbound-only restrictions during the overnight windows.

Night-by-night schedule (I-205 southbound)

• Friday, July 31 (11 p.m.) to Saturday morning, Aug. 1 (7 a.m.) — I-205 southbound closed between MP 8.50 and MP 9.56.
• Saturday, Aug. 1 (11 p.m.) to Sunday morning, Aug. 2 (7 a.m.) — the same I-205 southbound segment remains closed overnight.
• Weekend of Aug. 7–8 — additional overnight southbound closures are planned in the same area on the 11 p.m. to 7 a.m. windows, including the Saturday night of Aug. 8.

Ramp impact: OR 99E on-ramp to I-205 southbound

In addition to the freeway closure, the project site says the OR 99E on-ramp to I-205 southbound is scheduled to close from 10 p.m. to 8 a.m. during the same overnight direction-closure windows on the July 31 and Aug. 1 nights.

Detours for southbound travel

During the overnight closures, the project site recommends:

• Regional southbound detour: use I-5, I-84, and the Ross Island Bridge.
• Local river crossing: use the Arch Bridge for local traffic.

How to check day-of updates

For last-minute changes, look at TripCheck’s I-205 MP 8.50–9.56 entries for your travel day. If you normally rely on the OR 99E → I-205 southbound ramp, build extra time and avoid last-minute on-ramp decisions during the 10 p.m. to 8 a.m. closure window.
