Columbia/Lombard Mobility Corridor Plan
The Columbia/ Lombard Mobility Corridor Plan is a multimodal plan to address safety, mobility, and access for freight, active transportation, and public transit both along the corridor (east/west) and across it (north/south). The project area, which runs from I-5 to I-205 with a buffer area to include parallel routes. The project is slated to begin January 2019 with a duration of 18 months, ending in summer 2020.

NE Columbia Blvd and NE Lombard St, running parallel on opposite sides of the Kenton Line railroad, are vital links in the regionally-identified mobility corridor running east and west between the I-5 and I-205 freeways. According to the Regional Transportation Plan, mobility corridors should function well as a whole for all modes of transportation, though different modes may be prioritized to a greater or lesser degree on different facilities within the corridor. Due to aging infrastructure, gaps and deficiencies in the multimodal network, growing traffic congestion, major safety issues, and longer commuting distances, the Columbia/Lombard Mobility Corridor is not functioning as well as it should for the freight, transit, and active transportation modes that our policies tell us should be high priorities. All users would benefit from improvements that would enhance mobility and access, provide greater connectivity, and reduce conflicts.
Specific problems and issues of concern include:
- A lack of separation between modes, outdated roadway designs, and sub-standard infrastructure have led to major safety issues on both Columbia and Lombard. Both streets are on the designated Vision Zero High Crash Network because of high crash rates, especially those involving motor vehicles.
- The pedestrian and bicycle networks have major gaps and deficiencies and transit service is currently very limited, which means most commuters or visitors are reliant on personal vehicles that add to traffic congestion and increase cost of living.
- Residents of nearby neighborhoods in Northeast Portland have difficulty accessing jobs, parks, and services in the area due to widely spaced and difficult connections across the corridor.
- Proposed TriMet bus service on Columbia Blvd would be difficult to access because the street currently lacks adequate pedestrian facilities, crossings, and connections to employers.
- At-grade railroad crossings, sub-standard over-crossings, missing connections and signals, and traffic bottlenecks have led to growing concerns about freight mobility and access in the corridor.
- The lack of traffic management systems means that freight operators and personal drivers alike do not have adequate information to respond to congestion issues and choose the most optimal routes.
- The corridor does not currently have a clear system of mode-specific treatments that would prioritize freight and transit over single-occupancy vehicles.
Plan Scope and Outcomes
The proposed Columbia/Lombard Mobility Corridor Plan will identify, develop, and prioritize improvements that would make multimodal transportation and freight movement safer and more efficient along the corridor. Specifically, the proposed plan will include the following scope elements:
- Conduct a corridor-wide mobility and access analysis to identify freight needs and potential solutions, including facility upgrades, new or improved connections, traffic management systems, priority treatments, and operational improvements.
- Identify and prioritize access to transit and employment investments that support planned future bus service on Columbia Blvd, create last-mile connections to employers, and provide pedestrian and bicycle access from nearby neighborhoods.
- Develop a Vision Zero strategy that includes context-sensitive safety solutions that prevent conflicts and improve safety for all modes while maintaining the ability for freight and transit to move efficiently and reliably.
- Develop conceptual designs and cross-sections for Columbia, Lombard, and connections between them to provide clarity and direction for future capital projects, paving projects, and development review.
- Recommend project and program priorities for the Transportation System Plan and develop an implementation strategy to ensure that the Columbia Corridor receives needed investments in a reasonable time frame.
