Why is this study needed?

Route 23 already has 30% more traffic than the roadway was designed to accommodate, leading to increased congestion, unpredictable travel times, bottlenecks, and higher crash rates. This study will also support Columbus as a national logistics hub by strengthening connection and access to northwest Ohio, Michigan, and Canada.

What is the process?

Route 23 Connect Phase B builds upon analysis and engagement of Route 23 Connect Phase A, which considered possible free-flow connections between Waldo and I-270. The Phase A Executive Summary can be found in the Document Section of this website. The cost, complexity, and environmental impact of the concepts presented in Phase A were too high to pursue further so the study is shifting its focus toward identifying smaller-scale improvements.

Phase B of the Route 23 Connect Study will focus on improvements along the U.S. 23 corridor between I-270 and Waldo. This evaluation will inform an action plan that pinpoints specific new project concepts that can be advanced to the project development phase. These new project concepts will range in size and scope, aiming to provide safer and more efficient travel, including increased travel time reliability for through traffic. Concepts studied will be implementable within a timeframe that will provide drivers with benefits sooner rather than later.
