Project Background

The interchange of US-52 and SR-93 is located in Upper Township and the City of Ironton, Lawrence County. SR-93 is a minor arterial with a posted speed limit of 35 mph and US-52 is a four-lane freeway with a speed limit of 60 mph. The US-52/SR-93 Interchange is a partial cloverleaf/diamond configuration with direct ramps for the eastbound direction and loop ramps and one slip ramp for the westbound direction. The two ramp terminal intersections are approximately 580 ft. apart and each has a diagonal span wire signal installation.

Both intersections have experienced a high number of rear-end crashes on southbound SR-93.  The location was ranked #45 on the ODOT 2017 Highway Safety Improvement Program (HSIP) suburban intersection list and was on the 2019 Governor’s Top 150 Safety Location List. The location was ranked #428 on the 2018 HSIP suburban intersection list and SR-93 from SLM 1.44 to 1.47 (the north approach to the eastbound ramp intersection) was ranked #1221 on the 2018 HSIP urban freeway list. The crash data between 2013 and 2017 indicated 64 crashes occurred in the study area with rear-end crashes (73%) and injury crashes (33%) being over the statewide average for state route non-freeway locations.

Purpose and Need of the Project

The interchange of US-52 and SR-93 is located in Upper Township, bordering Ironton city limits in Lawrence County. The study area includes the two signalized ramp terminal intersections along SR-93 on either side of US-52. The Ohio Department of Transportation’s (ODOT) 2017 Highway Safety Improvement Program (HSIP) ranks this location #45 on its list of suburban intersections and it was listed on the Governor’s Top 150 Safety Location List. Since the location identifier is measured along US-52, the two intersections are combined for the purpose of ranking. It should be noted that this location is listed as stop-controlled on the HSIP list, and therefore the listed predicted and expected crashes, as well as the potential for safety improvement are likely using inaccurate inputs for calculations since both intersections are signalized.

The crash data between 2013 and 2017 was provided by ODOT District 9, with a few additional crashes found on ODOT’s TIMS website. The interchange area has experienced similar crash patterns over time and has been studied previously. A recent resurfacing project included a turn lane addition and striping and signing changes. The purpose of this study is to analyze the existing safety performance of the intersections and to identify potential countermeasures to reduce crashes and continue to improve overall safety.

Alternative Evaluation

The following are the two alternatives identified in the 2019 Safety Study:

  • Alternative 1: Traffic Signal Upgrades (Medium Term)
    • Add backplates to all signal heads, reduce crashes by up to 15%
    • Add a supplemental southbound signal head to the US-52 Eastbound ramp terminal, reduce crashes by up to 7% (applied to southbound approach only)
    • Modify yellow change and all-red clearance intervals, CMF varies between 0.63-1.08 by crash type

 

  • Alternative 2: Roundabouts (Long Term)
    • Convert two signalized intersections to single-lane roundabouts, reduce injury crashes by up to 71% and property damage crashes by up to 26%

Virtual Public Meeting - February 9, 2021 at 5 p.m.

Due to the COVID-19 pandemic outbreak, Ohio's Governor Mike DeWine has prohibited mass gatherings and the CDC has recommended using social distancing to help prevent the spread of the COVID-19 virus.  Public involvement meetings are very difficult to perform while practicing social distancing.  Due to these issues, ODOT is now conducting public involvement meetings virtually so that social distancing can easily be performed while engaging with the public about transportation projects.

Internet Access Difficulties

A transcript of the video presented here and a printout of exhibits will be provided to anyone who has issues accessing the virtual public meeting.  Please request a transcript from Matthew McGuire of ODOT District 9 for the U.S. Route 52 & State Route 93 Intersection Improvements (PID 111487) virtual public meeting by one of the following methods:

View Project's Public Comments ()

Public comments regarding our projects are always welcome!

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.

Please let us know if you have questions, and thank you for your interest and input on the project!
