Indian River Lagoon-Treasure Coast Scenic Highway

The byway includes section of two iconic American roadways: A1A and US1. US1 on the mainland taking you through Fort Piece and Port St. Lucie. A1A on the barrier island takes you along the Atlantic Ocean. What makes this byway extraordinary is the view from the sandy, coastal dunes that drift out into the Atlantic Ocean to the mangrove-covered banks of the Indian River Lagoon – home to more than 4,000 species of plants and animals, including 50 species that are endangered or threatened. This corridor is more than a paved path that takes you from Point A to Point B. It’s an educational experience designed to enhance St. Lucie County’s remarkable historical, cultural, and environmental resources.
