LOUISVILLE, Ky. (WDRB) — There has been an overall decline in crashes on Louisville roads reworked for safety reasons over more than a decade, a new report has found. The report from the Kentucky Transportation Center analyzed city- and state-managed “lane diets,” road alterations and other measures since 2009, noting that total crashes, speed-related crashes and pedestrian collisions all fell in places with at least a year of before-and-after data.
