Lane closures on State Road 16, U.S. 1 and other St. Johns County roads begin Monday, Oct. 19. The Florida Department of Transportation (FDOT) scheduled the work through Friday, Oct. 23, for ongoing construction projects.

The St. Augustine Record reported that several roads will be partially closed at various times during the week. One closure starts a day early: SR 16 between Race Track Road and Circle Drive East has nighttime lane closures beginning Sunday, Oct. 18, through Thursday, Oct. 22, from 8 p.m. to 6 a.m.

That stretch has seen the same closures for at least two consecutive weeks.

Other closures that could affect commuters in the St. Johns and Fruit Cove areas:

  • County Road 312 at U.S. 1: Daytime lane closures Monday, Oct. 19, through Thursday, Oct. 22, from 9 a.m. to 3 p.m. for road work.

Nighttime closures also affect downtown St. Augustine corridors Monday through Thursday:
