Evidence Log
😈 **Devil's Advocate Critique:** Recent federal funding infusions (e.g., FHWA $700M, Trump I-95 project) and zero new incidents in early April further demonstrate effective management and investment, suggesting infrastructure neglect claims are overstated amid steady metric improvements and proactive agency actions.
No new national bridge or dam condition reports from FHWA, ARTBA, ASCE, or USACE in early April 2026; latest data remains mid-2025 [web:16][web:17][web:18]

No reports of major US bridge collapses, dam failures, or significant infrastructure incidents from April 1-12, 2026, across web and X searches [web:0]
😈 **Devil's Advocate Critique:** Persistent YoY metric improvements, IIJA/IIJA-extended funding deliveries, proactive USACE/ASCE actions, and absence of major failures despite warnings suggest competent management over systemic neglect; reauthorization likely to bridge any cliff.

😈 **Devil's Advocate Critique:** Steady declines in poor infrastructure metrics, IIJA-driven gains (e.g., bridge poor count down ~390 YoY), and proactive state actions (e.g., MI dam reforms) indicate effective mitigation rather than neglect; funding cliff manageable via reauthorization.
