ODOT began the Route 23 Connect corridor study in Spring 2021 to determine the feasibility of creating a fully free-flowing connection between the Columbus and Toledo regions. The study centered around the portion of U.S. 23 between Waldo and I-270, which is the only portion of the I-75/U.S. 23/SR 15 corridor with traffic volumes exceeding roadway capacity. The study area includes nearly 40 traffic signals, the only signals between I-270 and Toledo. 

Seven concepts were developed and analyzed in the first phase of this study, including a no-build option, upgrading the existing U.S. 23 corridor to free-flow, two new freeway connections to U.S. 33 to the west, and three new freeway connections to I-71 to the east. Each concept was evaluated using a variety of metrics to analyze travel times, safety benefits, community impacts, environmental impacts, and cost. 


After comparison of the expected benefits and costs for each Phase 1 concept, we have determined none of the concepts as presented can be reasonably implemented. The concepts presented would cost at least three times more than the benefits it would provide and each of the proposed concepts would substantially impact community and natural resources.

Instead, the study is shifting its focus to planning and implementing a series of stand-alone improvement projects along the existing U.S. 23 corridor between Waldo and I-270. The next phase of the study will inform an action plan that recommends and prioritizes specific projects along U.S. 23 to provide safer and more efficient travel, including increased travel time reliability for through traffic.

All materials from Phase 1 of the study can be found here.

This section is for frequently asked questions and project-related questions. You may notice that some projects require one or more formal comment period(s) with deadlines for comments to be considered during certain phase(s) of the project development process. Typically called the “public comment period," this is when ODOT asks the public for input before an important decision needs to be made, such as choosing a preferred alternative. You may notice these periods generally occur immediately following a public meeting.

All comments received, regardless of when or how they are submitted, will be reviewed and considered and/or responded to by the ODOT project team. Comments received through this forum will, when appropriate, be publicly posted along with ODOT’s response; Such comments will be moderated to remove personal information prior to posting.
