Project Benefits


The purpose of this project is to reduce delay, improve traffic operations, and improve the intersection Level of Service (LOS) within the project limits.


Due to the current all-way stop control, the intersection of SR 140 and SR 165 is experiencing significant delay, poor operations, and an unacceptable LOS during peak hours.
