PennDot is planning installation of chevron curve signs along selected roads in Washington, Greene, Fayette and Westmoreland Counties. They will also be performing tree trimming along those roads. The purpose of the installation is to improve safety along roads with distinct curves. According to PennDot, studies show a significant decrease in accidents along curves when drivers have been given early notice. In Washington County, four areas will have roads addressed with signs. PennDot is asking for feedback until February 24. Maps of the proposed sign construction and an area for feedback on the project may be found here. Construction of signs is expected to begin in the spring.
