Puerto Rico Highway 344 is a rural road located in Hormigueros, Puerto Rico, beginning from near the small downtown of the municipality and ending in PR-348 near the border with San Germán in the Rosario barrio. It has narrow lanes and after about five kilometers it turns to be one of the most dangerous highways in Puerto Rico, as it goes near a precipice with little or no safety barriers. The route serves as a route to Mayagüez via PR-348 which ends in Puerto Rico Alt Route 2 (Calle Ramón Emeterio Betances, or locally Calle Post).
