A waterfront bridge on San Antonio Bay provides critical access that no other structure can — spanning water and terrain that cannot be filled or graded. The bay's brackish water from Guadalupe and San Antonio Rivers conditions, soft mud and delta sediment foundation, and southeast wind fetch, river flooding cycles, hurricane surge determine span design, piling depth, and material selection.
Shore Protect Team builds bridges from treated wood, steel, and aluminum — selecting the material that matches the span, loading, and exposure. Pilings are driven to refusal or engineered depth in the bay's soft mud and delta sediment. Walkway and boardwalk approaches are integrated to provide seamless access from the bridge to the waterfront.

Bridge repair along San Antonio Bay: evaluating pilings in soft mud and delta sediment, replacing decking and framing, upgrading hardware, and restoring structural capacity. Shore Protect Team determines whether repair or replacement is the right approach for each crossing.
Treated wood is the most economical for shorter spans on San Antonio Bay. Steel provides the greatest load capacity for longer spans and vehicle traffic. Aluminum offers the longest lifespan with minimal maintenance. Material choice depends on span length, loading, and exposure to southeast wind fetch, river flooding cycles, hurricane surge.
Starting at $35/sq ft for new construction and $25/sq ft for repair on San Antonio Bay. Final cost depends on span length, width, load rating, material, piling depth in soft mud and delta sediment, and any railing or lighting requirements.
San Antonio Bay is subject to southeast wind fetch, river flooding cycles, hurricane surge. Bridges must be designed with adequate flood clearance above the design water surface elevation. Pilings and abutments must withstand scour forces from flood current in soft mud and delta sediment substrate.
If pilings and primary structural members are sound, most decking and railing damage can be repaired. If pilings have settled, corroded through, or been undermined by scour in soft mud and delta sediment, full replacement is usually the better investment.
