El Rosario Airstrip

The specific reason for closure is not publicly documented, which is common for small, private airstrips in Mexico. The most likely cause is economic, such as the airstrip no longer being financially viable for its private owner to maintain, or a change in the ownership or use of the surrounding land (e.g., a ranch or farm closing or changing hands). While the region has seen military operations against clandestine airstrips used for illicit activities, there is no direct evidence (such as destructive trenching by the military) to suggest this was the reason for the closure of MX-0446. The gradual decay suggests simple abandonment.

The airport is definitively closed and non-operational. Recent satellite imagery shows the runway is heavily overgrown with grass and shrubs. The path of the runway is still clearly visible but is now used as an unpaved local road or track for vehicles. The surface is degraded and unsuitable for any aircraft operations. There are no visible airport facilities like hangars or terminal buildings remaining.

El Rosario Airstrip was a small, private airfield of local importance. Its primary function was likely to serve a nearby ranch (hacienda), agricultural operation, or private business. With a dirt/gravel runway approximately 1,100 meters (3,600 feet) in length, it could accommodate a variety of general aviation aircraft, from single-engine planes to light twin-engine turboprops like the Cessna Caravan or King Air. Operations would have consisted of private transportation of personnel, supplies, or potentially agricultural aviation (crop dusting). It did not handle any commercial, scheduled, or significant military air traffic.

There are no known or published plans to reopen the El Rosario Airstrip. Given its remote location, private nature, and current state of disrepair, the prospect of it being rehabilitated and reopened for aviation is extremely low. It would require significant private investment and a renewed economic purpose for its existence, which currently does not appear to exist.
