TEMPORARY CLOSURE ORDER - UPDATE
Pursuant to the authority outlined in 36 CFR § 1.5(a)(1), which provides that the Superintendent may "Designate areas for a specific use or activity, or impose conditions or restrictions on a use or activity," the following areas are restricted or closed:
All crossover roads leading south from South Puerto Blanco Drive
Grey's Ranch Road
Camino de Dos Republicas
An area encompassing the southern boundary of the Monument adjacent to Mexico, extending from the border shared with the Tohono O’odham Nation in the east, to the border shared with the Cabeza Prieta National Wildlife Refuge in the west. Beginning at the primary international border fence, this area extends northward for 150 feet. The only exceptions to the 150-foot distance would be at locations where the planned construction footprint is aligned closer to the international border (e.g., Quitobaquito, etc.)
This closure is effective August 24, 2026 and will remain in effect until further notice.
This closure is in furtherance of the Department of Homeland Security infrastructure project as authorized under the Illegal Immigration Reform and Immigrant Responsibility Act (IIRIRA), Pub. L. No. 104-208, Div. C., Title I, § 102(a), 110 Stat. 3009-546 (1996) (codified at 8 U.S.C. § 1103 note). It is intended to mitigate considerable risk associated with an active, large scale construction project and applies to all vehicles and pedestrian traffic.
Visitor education materials and alerts will be made available throughout the closure period. The effectiveness of this closure will be assessed on an on-going basis. Notice will be provided of any additional closures, or the lifting of this closure.
