Puerto Caleta La Misión, Maritime port in Río Grande, Argentina

Puerto Caleta La Misión is a halted port project on the Argentine Sea, 12 km north of Río Grande on National Route 3. Its planned offshore dock was to be reached by a 1,620-metre viaduct on piles, with a 460-metre breakwater of 231,000 m³ sheltering the pier.

The project began in December 1997 with planned construction, but financial difficulties caused work to halt by late 1998. This led to prolonged legal disputes and multiple attempts to revive the project.

The name Caleta La Misión comes from the cove on the Argentine Sea where the dock was planned. The 2011 decree granted a 40-year concession to operate the port, with a purchase option every five years, and the work was to be funded by the Fideicomiso Austral, fed by oil royalties. The provincial legislature rejected that decree in September 2012.

The site is accessible from National Route 3 and provides access to the southern coastal area of Tierra del Fuego. The location sits in a windy region with rough sea conditions that require proper preparation for visits.

The facility remains incomplete for decades, with visible construction structures bearing witness to halted work and financial struggles. This abandoned infrastructure tells the story of ambitious projects that failed to materialize in the remote southern region.
