Those are common street names in Santo Domingo. You've got both in Ensanche Espaillat but they don't quite corner. It would be on the left before the Francisco del Rosario Sanchez bridge.
You've also got both in Ensanche Isabelita but they're parralel. They're on the left hand side on Ave. Espa?a, a bit after the Acuario, on your way out of SD.
