NC12 interim‑bridge study recommends evaluating cord‑slab, modular and timber options ahead of long‑term TIP projects
Summary
Consultant Jim Trogden told the board an interim bridge strategy for Highway 12 hotspots should evaluate cord‑slab, modular 'panel' and timber bridge types; DOT coordination, industry outreach and a prioritization of hotspots will begin immediately, with funding analysis planned in August and a completed plan aimed for early October.
A consultant working with the county on Highway 12 hotspot problems described an interim‑bridge strategy that evaluates multiple short‑to‑medium‑term bridge options while longer state TIP projects remain in the queue.
Jim Trogden (Greer Brady) said his team has completed industry outreach and initial DOT coordination and will begin a hotspot review and prioritization process, considering cord‑slab bridges (traditional concrete), modular panel (the so‑called 'Lego' bridge) and timber bridge options. The goal is to identify solutions that can be installed within existing rights‑of‑way to avoid long permitting delays and provide more reliable access and travel‑time improvements for barrier‑island communities.
Trogden said task‑three (hotspot review and prioritization) would start immediately, followed by a funding analysis and strategy in August; the team hopes to present a plan by early October to give the county options for interim bridging and inputs for state and federal funding outreach.
Why it matters: Highway 12 serves as a critical access corridor for the county’s barrier islands and local economy; interim bridging that reduces overwash vulnerabilities and improves reliability could reduce disruption while the DOT’s long‑range fixes proceed through the TIP process.
