Texas turned a demolished 6,620-foot bridge into a 320-acre artificial reef

Texas has transformed material from the demolished Queen Isabella Causeway into a new 320-acre artificial reef near South Padre Island. The 6,620-foot bridge once connected Port Isabel and South Padre Island and had already provided habitat for fish and invertebrates before its retirement.

Its western section later became a safety and navigation concern, prompting the Texas General Land Office to oversee its removal. Rather than treating the old bridge material as waste, the project repurposed it offshore as a long-term marine habitat.

The Texas Parks and Wildlife Department’s Artificial Reef Program handled the reefing plan, material-placement protocol, and creation of the new reef, which was completed in July 2026.How the 6,620-foot Queen Isabella Causeway became a new offshore artificial reefThe Queen Isabella Causeway was built in 1954 and served for two decades as the main route between Port Isabel and South Padre Island. According to the Texas General Land Office (GLO), the 6,620-foot bridge also unintentionally functioned as artificial reef habitat for fish and invertebrates.
