According to police crash report data from 2020 to 2022, there were approximately 280,000 crashes in Connecticut, and 34,000, or 12 percent, occurred on curves on state or town roads. In an effort to curb car accidents and deaths, the state Department of Transportation is updating and installing new horizontal curve warning signs and speed advisories on local roads throughout 15 towns in northwestern Connecticut. While fatal crashes make up less than 1 percent of crashes in the state, a third of them happen on curves, she said. So, the project takes a proactive approach by installing warning signs to improve driver awareness in response to curves. Numerous studies have concluded that by installing arrows, chevrons, and curve warning signs, crashes can be reduced anywhere from 30 to 50 percent, according to the DOT presentation. And signs are considered a relatively low-cost countermeasure with quick installation. The estimated construction cost for this project across the 15 towns is approximately $305,000, covered completely by federal funds. The construction cost includes the actual sign installations and removals, Police traffic control along the road, and trimming of tree branches near signs.
