Overnight Closures Planned for I-5 and OR 43 as Portland Enjoys Sunny Saturday

Weekend Road Conditions: Overnight Closures and Clear Skies

Portland travelers can expect a relatively smooth Saturday morning, though the Oregon Department of Transportation (ODOT) has several key ramp closures scheduled for the late-night hours. With clear, sunny skies and a high of 43 degrees, daytime visibility will be excellent, though commuters should remain alert for ongoing maintenance and lane restrictions on major arteries.

Major Highway Alerts

• I-5 Southbound: Tonight, the Exit 300B off-ramp to US 26, OR 99E, and OMSI will be fully closed from 9:00 PM until 6:00 AM Sunday morning. Drivers heading toward Oregon City or the Ross Island Bridge should plan for detours during these hours. Additionally, nightly width restrictions of 14 feet 5 inches are in effect between MP 302 and 301 near the Rose Quarter through early February.
• I-84 Westbound: The off-ramp to I-5 Southbound, which was closed Friday night for sign replacement, has reopened as of 4:00 AM this morning. However, maintenance crews continue to work near the Lloyd Boulevard intersection, where the center lane may be closed. Expect minor delays of under 20 minutes in this area.
• I-205/OR 43: In West Linn, the OR 43 southbound off-ramp to I-205 northbound is scheduled to close tonight at 10:00 PM and will remain closed until 8:00 AM Sunday.
• Highway 6: The route between Portland and Tillamook is now open to two-way traffic following landslide repairs. However, ODOT advises drivers to watch for flaggers and be prepared for minor delays as final safety measures are completed.

Portland City Streets and Safety Projects

Within the city limits, the Portland Bureau of Transportation (PBOT) continues safety and ADA compliance upgrades. On NE Glisan Street, crews are active between NE 82nd and 92nd Avenues rebuilding sidewalk corners. While much of the heavy paving is slated for the coming summer, minor lane shifts may occur today as contractors prepare crossing points.

On US 30 (NW St. Helens Road), travelers should anticipate periodic daytime lane closures between NW Bridge Avenue and NW Kittridge Avenue for signal replacements and repaving. Bicyclists are advised to use the roadway travel lanes in this construction zone as pedestrian detours are in place.

Public Transit and Commuter Reminders

TriMet is reporting standard Saturday schedules for the MAX Light Rail and bus lines today. Commuters who utilize Line 24 (Fremont) or Line 8 (Jackson Park) are encouraged to review the upcoming service changes proposed for later this spring. The public comment period for these budget-related service reductions remains open until January 31, 2026.

With morning temperatures starting near 30 degrees, bridges and overpasses may have localized slick spots despite the dry forecast. Drive with caution and allow extra following distance during the early hours.
