Queen Isabella Causeway after Dark Pano – Looking out on the Queen Isabella Causeway after dark you can still see a little color left in the sky from the sunset earlier in the evening. This bridge is two miles long and is the only route in to South Padre Island. The light on the bridge are reflecting back in the water after dark. The Queen Isabella Causeway is about two miles long and is the sole source for getting to the island from the mainland by vehicals. In 2001 a barge hit the bridge and destroyed a 160 foot section and till it was rebuilt the people had to travel by ferry to get to and from the island for several months till it was repair. Also a special note for those who lost their lives on that tragic night.
