Highway safety enhancements coming to A1A south

Motorists and bicycle riders alike will soon benefit from enhanced safety features along 15 miles of A1A south from Ponte Vedra Beach to Vilano Beach. Rumble stripes will be ground into the roadway’s shoulder and center lines, helping to prevent collisions on the highway.

The rumble striping project is scheduled to start Sunday, April 10 and is expected to be complete in four weeks, schedule and weather permitting. Moving lane closures are scheduled Sundays through Thursdays, from 6 p.m. to 6 a.m., from north of Carcaba Road in Vilano Beach to south of Mickler Road in Ponte Vedra Beach. Law enforcement will be on site. Drivers are urged to use caution when approaching the work areas.

A1A Rumble Stripes

Rumble striping is a safety improvement to reduce the frequency of crashes involving vehicles leaving their lane. The grooves cause a vibration and sound when drivers drift from their lane, lessening the likelihood of vehicles running off the outside shoulder as well as vehicles crossing the center line.

The rumble striping on the shoulders will alternate 7 feet of rumble and 5 feet of open space to allow bicyclists to cross the shoulder when needed.

The project includes removing the existing striping, painting the lines back each night, cutting in the rumble, painting and replacing the reflective Raised Pavement Markers (RPMs).

“Rumble stripes are a cost-effective and proven method that can help save lives,” says Jeff Scott, Florida Department of Transportation (FDOT) safety engineer. “We look forward to completing this project on A1A for the benefit of drivers, pedestrians and bicyclists in our community.”

This is FDOT’s first rumble striping project in the northeast Florida area to place the rumble line on an existing road. Future resurfacing projects on roads with a 50 mph or more speed limit, and with no curb and gutter, will include rumble striping in the project scope.
