Additional SR 99 Closures This Spring
The closures that began in mid-January on SR 99 are over for now, but according to SDOT, more lane closures are coming this spring.
The most recent closures were to install a 7,000 pound metal sign foundation. The next set of construction will be to install the signs for the future tunnel. This project may require partial or full directional closures. No word on when the project will begin. (But the first day of spring is March 20.) We will keep you posted.
