Commission recommends approval for CSX bridge replacement in Grand Plains Bayou
Summary
Coastal Resources staff recommended and the commission recommended the executive director approve CSX's request to replace a single‑track rail bridge with a two‑track bridge in Grand Plains Bayou, including a limited riprap placement and a use‑plan change; HDR representative clarified the project would remove the old bridge and install a new, two‑track structure.
Coastal Resources staff told the commission that CSX Transportation has requested a certificate of waiver and a use‑plan change to replace an existing single‑track railway bridge in Grand Plains Bayou (Hancock County) with a wider, two‑track bridge. Katie Nelson told commissioners the applicant proposes to expand a 120‑by‑40‑foot footprint to approximately 144 by 44 feet and to place a small amount of riprap (0.00481 acre reported in presentation) for shoreline stabilization.
Katie Nelson said staff found "no significant environmental impacts" and recommended the commission recommend the executive director approve the use‑plan change to special use district S6 and issue the requested waiver. HDR representative Daniel Leair said the project will remove the existing one‑track bridge and construct a new two‑track bridge; he estimated the navigation channel would be closed for about one month during construction, depending on the contractor's schedule.
Commission discussion focused on whether the project is an expansion or replacement; staff clarified the existing bridge would be removed and replaced with a new bridge to accommodate two tracks, and commissioners asked about benefits such as accommodating longer trains and potential Amtrak operations.
The commission moved, seconded and approved the staff recommendation by voice vote.
Why it matters: The project touches navigation and shoreline stabilization in a preservation district; the staff justification cites public and environmental safety by ensuring rail infrastructure is safe and reliable.
What happens next: The commission recommended the executive director approve the waiver and use‑plan change; staff and the applicant will coordinate construction timing and any navigation aids with the U.S. Coast Guard as conditions require.
