The Connecticut Department of Transportation will be resurfacing Route 104 (Long Ridge Road) from 0.28 miles north of Route 15 to 0.11 miles south of Riverbank Road during the 2018 construction season. It was determined that the sections of Route 104 between just south of Northwood Lane to just south of Riverbank Road, a distance of approximately 2.70 miles, is a candidate for the installation of centerline rumble strips. The Department is requesting the City’s approval for the installation of centerline rumble strips in this area. The City would like your feedback related to the desirability of centerline rumble strips in your community. I’ve provided more information below about centerline rumble strips so that you may understand their benefits. While they are a proven safety countermeasure, they do have drawbacks. External noise caused by traffic crossing rumble strips may negatively impact communities as they may disturb adjacent homeowners and may affect protected wildlife species.
“Centerline rumble strips (CLRS) are a cost-effective, proven safety countermeasure that reduces the risks of headon and sideswipe opposite direction crashes. A CLRS is a longitudinal safety feature installed at the centerline of a paved roadway. It is comprised of a series of milled elements intended to alert distracted, drowsy or inattentive drivers (through vibration and sound) that they have unintentionally crossed the centerline. For those drivers who unintentionally cross the centerline, the audible and vibratory warning provided by the CLRS greatly improves the chances of a quick and safe return to their lane. Where drivers do not safely recover, the warning created by the rumble strips often improves driver reaction; reducing crash severity. CLRS also serve as an effective means of locating the travel lane during inclement weather. Pavement markings are often obscured during fog, snow or rain. The vibration provided by CLRS can assist drivers from unintentionally crossing the centerline during these conditions.”
Please find a link (http://www.ct.gov/dot/cwp/view.asp?a=3199&q=526532) to information and photographs of Centerline Rumble Strips (CLRS). I’ve also attached CTDOT’s specifications for reference.
We look forward to your feedback! Please do not hesitate to contact me if you have any questions.
