NW Cornell Road Reopens Near Tunnels, West Section Remains Closed – Portland, OR

Portland residents are breathing a collective sigh of relief as a section of NW Cornell Road has reopened earlier than anticipated. The reopening follows a swift response to a landslide that impacted the key Northwest Portland artery last Friday. While full access isn’t yet restored, the progress is a welcome sign, especially for those relying on this route to reach the Bird Alliance of Oregon and surrounding neighborhoods.

Landslide Response and Initial Closures

The initial landslide, occurring between the two tunnels on NW Cornell Road, brought traffic to a standstill and prompted immediate closures by the Portland Bureau of Transportation (PBOT). The situation was complicated by downed trees and compromised power lines, requiring a coordinated effort from multiple agencies, including Portland General Electric and Portland Parks & Recreation Urban Forestry. Crews worked diligently throughout the weekend to clear debris, assess the stability of the hillside, and make the area safe for reopening. A separate, ongoing closure remains in effect further west on NW Cornell Road, between NW Thompson Road and NW Skyline Boulevard, stemming from a landslide and sinkhole discovered on March 13th.

A Collaborative Effort to Restore Access

The speed of the reopening between the tunnels is a testament to the collaborative spirit of Portland’s city departments. Portland General Electric crews quickly secured the power lines, allowing foresters to remove hazardous trees. PBOT crews then moved in, removing an impressive 24 dump truck loads of soil, rock, and vegetation. City engineers conducted thorough safety inspections both on Friday and Monday, identifying and removing any remaining unstable trees. A protective erosion control matting was then applied to the slide area, a crucial step in preparing for the forecasted rainfall on Wednesday. The removal of detour signage, which had extended as far east as NW 23rd Avenue and Lovejoy Street, signaled the successful completion of the initial phase of repairs.

Navigating the Remaining Closure

While the reopening between the tunnels is positive news, travelers heading west on NW Cornell Road still face a significant detour. The closure between NW Thompson Road and NW Skyline Boulevard requires motorists to utilize alternate routes, including Highway 26, Highway 30, and West Burnside Road. PBOT strongly advises drivers to exercise caution and anticipate delays, particularly when navigating NW Skyline and Thompson Road as detours. The Bureau of Environmental Services is currently investigating and working to repair the damage to both the roadway and the stormwater infrastructure in the area of the western closure. This repair work is expected to take several months, according to PBOT.

Understanding the Broader Context of Landslide Risk

Portland’s hilly terrain and recent heavy rainfall have created a heightened risk of landslides throughout the city. Since March, PBOT has responded to at least half a dozen landslide events and other water-related damage to city streets. This underscores the importance of proactive infrastructure maintenance and emergency preparedness. The city’s vulnerability to landslides is a long-standing issue, and the recent events highlight the demand for continued investment in slope stabilization and stormwater management systems. The Bureau of Environmental Services plays a critical role in addressing these challenges, working to mitigate the risk of future landslides and protect Portland’s infrastructure.

The Importance of Reporting Road Hazards

PBOT emphasizes the importance of public cooperation in ensuring road safety. Residents are urged to report any road hazards, including landslides, sinkholes, or downed trees, to PBOT Maintenance Dispatch at 503-823-1700. Unfortunately, instances of individuals moving or violating barricades have hampered repair efforts, requiring crews to re-establish closures and, in some cases, replace barricades with more substantial concrete barriers. Respecting road closures and following the directions of flaggers and work crews is crucial for both public safety and the efficient completion of repairs.

Preparing for Future Weather Events

Portland’s weather can be unpredictable, and residents should be prepared for potential disruptions caused by severe weather. PBOT provides updates on winter weather road closures and chain advisories on its website. The city also offers resources to support residents prepare for heavy rain, snow, ice, and other severe weather events. Understanding the risks and taking appropriate precautions can help minimize the impact of these events on transportation and daily life. Staying informed and being prepared are key to navigating Portland’s challenging weather conditions.

Navigating Road Closures: A Local Resource Guide

Given my background in urban infrastructure and emergency management, I understand the stress and disruption road closures can cause. If you’re impacted by these ongoing issues in the Portland area, here are three types of local professionals who can provide valuable assistance:

Geotechnical Engineers: If you’re concerned about the stability of slopes on your property, or if you’ve noticed signs of potential landslides (cracks in the ground, leaning trees, unusual water drainage), a qualified geotechnical engineer can conduct a thorough assessment. Glance for engineers licensed in Oregon with experience in landslide hazard assessments and mitigation. They should be able to provide detailed reports and recommendations for stabilizing slopes and protecting your property.
Insurance Adjusters Specializing in Property Damage: Landslides and related damage can be covered by certain types of insurance policies. An experienced insurance adjuster specializing in property damage can help you navigate the claims process, document your losses, and negotiate a fair settlement with your insurance company. Seek an adjuster familiar with Oregon’s insurance regulations and with a proven track record of successfully handling landslide-related claims.
Transportation Planners & Advocates: For those interested in advocating for improved infrastructure and transportation solutions, a local transportation planner or advocate can provide valuable insights and resources. These professionals can help you understand the city’s transportation plans, identify areas for improvement, and participate in public hearings and community meetings. Look for planners with experience in landslide risk mitigation and sustainable transportation solutions.
