One of central Ohio’s most critical transportation connections.
Though the Online Open House comment period has completed, please feel free to review the materials. The feedback gathered in the Online Open House will help to direct the LinkUS: Northwest Corridor initiative.
The Northwest Corridor is one of central Ohio’s most critical transportation connections, linking major institutional and employment centers including The Ohio State University, the Ohio Health hospital campus, Grandview Yard, Downtown, and the Arena District. The corridor is accessible by State Route 315, paralleling Olentangy River Road and providing commuter connections from northwest communities to Downtown. This corridor initially emerged as a potential regional transit connection through the development of COTA’s NextGen plan (2017) — and was then selected for analysis as part of the Insight 2050 Corridor Concepts Study (2019).
The Northwest Corridor is one of the most physically complex of the corridors studied in Corridor Concepts. It includes two major interchange areas (the “Knots”) that present significant challenges to north-south through movement, and is physically constrained by the Olentangy River, the CSX railroad, and the highway.
Areas within the corridor, as well as in surrounding jurisdictions that rely on the Northwest Corridor for commuter access to and from Columbus, have experienced substantial new development in recent years, creating increased demand on mobility needs in the corridor. This new development, along with the many regionally significant employment centers and destinations, have led to congestion issues along the main artery of the corridor, SR 315. With the right combination of mobility infrastructure improvements and development patterns, there is an opportunity for the Northwest Corridor to enhance the region’s economic potential, access to jobs and quality of life.

Why the Northwest Corridor?
There are tens of thousands of jobs already in the corridor, with a high potential for job growth in the future.
The corridor links multiple major institutions and employers.
Congestion is already being experienced within the corridor on 315 and continued travel delay could limit opportunities for future mobility investment that could provide choice and mitigate congestion issues.
The Northwest Corridor presents some of the most complex challenges from an engineering and design perspective compared to other regional corridors.
The LinkUS partners developed a Northwest Corridor Foundations Report to showcase the need and vision for this initiative by exhibiting current conditions, trends, and other planning efforts relevant to the corridor. This is the first of a series of reports that will be developed to examine the issues facing the corridor and the opportunities to achieve regional goals through mobility investments and coordinated development strategies.
Explore the corridor
The Northwest Corridor plan process began in 2020 and includes five phases. The phases include stakeholder meetings and community engagement to identify the best choices for the corridor.
Collect critical data that creates the foundation for future analysis and recommendations.
Develop options for the corridor by building on the analysis of the foundational data.
The options are then evaluated using a technical analysis process designed to produce results to be shared.
The options and technical data are presented to project leadership, stakeholders, and the general public to determine a preferred option.
Document the results and present the final planning document. These items are endorsed by community leadership and used for action.
This effort is being led by the City of Columbus in partnership with the Central Ohio Transit Authority (COTA), the Mid-Ohio Regional Planning Commission (MORPC), and The Ohio State University. The process has additional funding partners including Nationwide Realty Investors, Franklin County, OhioHealth, and the Columbus Downtown Development Corporation, and other public and private funders.
