Drivers entering Fort Jackson through Gate 2 on Strom Thurmond Boulevard (Forest Drive) will soon have to find a temporary alternative and allow extra time for their commute.
The gate is scheduled for renovations Monday through Sept. 20.
It will be closed to all inbound and outbound traffic during that time.
The upgrades are part of an effort to accommodate traffic and meet Department of Defense regulations for security control access points on post.
The gate will receive additional lanes, existing lanes will be widened, and a new sign will be built. The total project has yet to be determined.
Officials are asking motorists to plan for delays during the renovation period.
Starting July 9, Gate 4, at Percival Road, will be open only for inbound traffic from 5 a.m. to 9 a.m. to help with morning traffic flow. The gate will be open around the clock.
