5500 Padre Blvd. Don't wait too long. This corner commercial lot on the main street of the fast growing South Padre Island will not last. With the exposure of HGTV in the last few years South Padre Island is growing fast. Now is the time to secure a commercial lot on the Main Boulevard of the Island. Turn North off the causeway 3 miles. On the corner of Padre Blvd & Cora Lee.
