The Naval Construction Battalion Center in Gulfport will be temporarily closed Monday for an on-base exercise.
The gates will be closed from 8:30 to 9:30 a.m.
The base also will be on lockdown during this time.
The exercise is an anti-terror drill.
Public Affairs Officer Rob Mims said in a press release U.S. Fleet Forces and Navy Installations Command will be conducting the annual Solid Curtain-Citadel Shield exercise at the base, as well as all at other Navy installations, from Jan. 30 to Feb.10.
Mims said residents near the Seabee Base also may see increased security activity associated with the exercise.
