ST. JOHNS COUNTY, Fla. – A major traffic shift on County Road 210 from Greenbriar Road to Cimarrone Boulevard began impacting drivers on Friday as St. Johns County crews work on a widening project.
From March 14 to March 23, neighborhood access might be impacted. Officials urged drivers to plan accordingly to reduce travel times and congestion.
According to the county, construction crews will divert traffic on the westbound lanes to the newly constructed roadway on Friday. Eastbound lanes will start diverting to the new roadway the following week.
“We understand this may cause some inconvenience, but these changes are necessary to ensure the safety and efficiency of the project,” said Greg Caldwell, director of public works for St. Johns County.
During the shift, drivers won’t be able to turn left into neighborhoods because of elevation concerns. Only right-hand turns into and out of neighborhoods will be allowed.
“It’s a temporary measure, but it will help us maintain a steady flow of traffic while ensuring safety,” added Caldwell.
Neighborhood access in the area will also be impacted, and drivers might have to divert and perform U-turns to reach their neighborhood. Temporary traffic signs and message boards will be posted throughout the area to indicate traffic pattern shifts.
“We ask for patience and understanding from the community as we work to improve the infrastructure,” said Caldwell. “Shear Water and South Hampton are on the south side. Still Water and Stone Creek are on the north side. But there are some residential homes that are located on the south side that will have to ramp up to access this new road system. But anything on the north side, you’ll still have open access. On the south side, is going to be limited just for that first week.”
Drivers are encouraged to be cautious as traffic adjusts to the new roadway configuration. During the transition, entering and leaving neighborhoods in this area will be easiest outside of peak times.
“Avoiding rush hours will definitely help ease the transition for everyone,” suggested Caldwell.
This is part of the $40-million widening project, which will add 2.3 miles of four-lane roadway, multiple new signalized intersections, sidewalks, and bike lanes to help alleviate congestion in this area.
The project is expected to be completed by May 2026 aiming to significantly improve travel times and safety for all road users.
“Once completed, this project will transform the way residents and commuters navigate this busy corridor,” emphasized Caldwell.
