Construction Work to Limit Parking at South Dakota Minuteman Missile National Historic Site’s Delta-01 and Delta-09 Sites


Cactus Flat, SD –  Work begins this month on a project to construct modern parking lots and restroom facilities a short distance away from both the Delta-01 Launch Control Facility and the Delta-09 missile silo. When completed at the end of the summer, these facilities will better allow access to the two sites for the visiting public with ample parking for buses and RVs.

At each location the new facilities will include a parking lot with car, bus and RV spaces, a comfort station, interpretive shelter, and pedestrian pathway connecting to the historic sites. These new facilities will be situated a respectful distance away from each site in order to preserve the historic landscape.

Visitors are advised that parking will be severely limited and large vehicle turnarounds will be difficult at both sites during this time. At Delta-01 visitors may park in four paved parking spaces. At Delta-09, parking will be limited to the driveway to the silo.

“These two facilities were built by the Air Force for a nuclear deterrence mission, and never intended for the public to see. This work is necessary to ensure that the historic sites are both better preserved and easier to access by the visiting public,” said Superintendent Eric Leonard, “We regret the inconvenience to the visiting public during the summer season.” To stay informed about this work and other news about Minuteman Missile National Historic Site, the public can visit our Facebook page or the park website for more information.

Minuteman Missile National Historic Site’s headquarters and visitor center is located off of exit 131, Interstate 90. The park consists of three sites along a fifteen mile stretch of Interstate 90 in Western South Dakota. Authorized by Congress in 1999, Minuteman Missile National Historic Site preserves components of the Minuteman II intercontinental ballistic missile system, interpreting the deterrent value of the land-based portion of America’s nuclear defense during the Cold War era and commemorating the people and events associated with this recent period of American history. The park is open daily 8:00 a.m. to 4:00 p.m. except Thanksgiving, Christmas, and New Year’s Day. More information about the park can be found on the internet at or by phone at: 605-433-5552.
