SR 37 & Strawtown Avenue Intersection Improvement
The project currently proposed for SR 37 and Strawtown Avenue includes a single lane roundabout with a central island featuring a mountable curb. A paved truck apron will allow larger vehicles, such as WB-65 tractor-trailers (more commonly referred to as interstate semi-trucks) to maneuver through the roundabout. Curbs and gutters will also be constructed throughout the roundabout limits. Construction of the project will require approximately 0.06 acre of new permanent right-of-way.
Purpose and Need
The need for the improvement comes from a goal to improve safety at the intersection by improving sight distance and reducing drivers’ speeds. Accident data suggest a significant number of right angle collisions due to Strawtown Avenue traffic crossing or turning onto SR 37 and although the speed limit was lowered from 55 mph to 40 mph in 2014, high speeds continue to be observed at the location.
The proposed roundabout will ensure a significant increase in safety, due to the fact that compared to traditional intersections, roundabouts cause an 82% reduction in fatalities and injuries and a 44% reduction in overall crashes.
The proposed maintenance of traffic plan for this project will allow SR 37 to remain open via the use of a temporary signal and by constructing one half of the roundabout at a time. Through movements along Strawtown Avenue will be restricted during construction. It is anticipated that each half of the project will require 45 days to construct, impacting traffic for approximately 90 days. Driveway access will be maintained to all local properties. School corporations and emergency services will be notified prior to any construction that would limit access.
