The work is scheduled each night starting on Monday, January 23 until Friday, February 10. Each night, work will start at 08:00 PM until 4:00 AM. The project is scheduled to be completed by Saturday, February 11 at 4:00 AM.

All work is weather dependent. The work may be extended or rescheduled due to inclement weather.

For worker and public safety, one-way-traffic-controls will be in effect during the work.

During one-way-traffic-controls, crews will alternate lane closures in the eastbound and westbound directions on SR-12. This will allow motorists to continue using SR-12 overnight.
