SR 37 Corridor Planning Study
SR 37 Corridor Planning Study
The Ohio Department of Transportation (ODOT) is performing a corridor study along State Route (SR) 37 between the City of Delaware and State Route 161. The objective of this study is to recommend potential solutions that would improve the existing roadway conditions along the SR 37 corridor and accommodate the anticipated traffic demands from future development and land use changes. The study’s primary objective is to focus on improvements that are feasible to implement within a 10-year timeframe.
The study has evaluated key intersections along SR 37 using the following methods and goals:
- Evaluate existing safety and congestion issues.
- Consider future demands based on anticipated increases in traffic (from planned developments, land use changes, associated Intel growth).
- Focus on solutions that are feasible to construct within the next ten years.
As this is a study, any recommended improvement will need to be funded before further design, environmental studies, and public outreach will occur.
Why was an in-person public meeting and virtual open house hosted?
The purpose of the public meeting was to discuss the project and recommended improvements with the community, answer questions, and gather community input before making final recommendations.
- The in-person public meeting was held on July 30, 2025 at Big Walnut High School.
- The virtual open house was held from July 30 through August 30, 2025. As of September 1, 2025 the website has been viewed over 3,400 times.
- The design team is currently reviewing your comments. Once addressed, a summary document will be uploaded to the Documents sidebar.
Thank you for your participation in this worthwhile study,
The formal public comment period is now closed. However, you comments are always welcome and can be submitted via the following methods:

Roadway Terms
In roadway design, an intersection approach refers to the segment of a road leading up to an intersection.
When a signal is coordinated, it means multiple traffic signals are working together in a synchronized manner to optimize traffic flow and minimize delays.
A free-flow intersection is designed to allow vehicles to move from one road to another without stopping or slowing down for traffic lights or other forms of traffic control.
Traffic signal phasing:
Overlap phasing lets certain movements —like a right turn— happen during more than one green light phase. For example, a right turn arrow might light up when vehicles from the side street are turning left.
With permissive left turn phasing, turning vehicles would be allowed to make turns during a green light, provided they yield to oncoming traffic and pedestrians.
Split phasing means giving each direction its own turn with a green light, one at a time. This helps reduce conflicts between left turns, pedestrians, and other traffic. However, it can make the total wait time at the light a bit longer for everyone, especially pedestrians.
Right in, right out refers to a type of intersection where vehicles can only enter and exit using right turns.
A left in movement is simply a left-hand turn, or the act of turning a vehicle to th eleft at an intersection.
A roundabout is a circular intersection where traffic travels counterclockwise around a central island. Entering traffic must yield to vehicles already circulating within the roundabout.
An RCUT (restricted crossing U-turn) is a type of intersection design aimed at improving safety on high-speed, divided highways by reducing the number of conflict points for vehicles. Instead of turning left or going straight across from a side road, drivers must first turn right onto the main road and then make a U-turn at a designated median opening further down the road.
A signalized RCUT intersection utilizes traffic signals to manage vehicle flow, while an unsignalized RCUT relies on signs (like stop signs) and driver judgment to determine right-of-way.
A skewed intersection is where two roads meet at a slanted angle instead of forming a typical 90-degree corner. This means they join together at a sharp or wide angle, making the intersection look more diagonal than square.
Lane continuity means traffic can keep flowing smoothy in a lane without needing to stop, merge abruptly, or change lanes unexpectedly.
