MODEL DATA NOTICE:
ASCE's 2025 national Inland Waterways grade is C−. ASCE's published 2024-33 economic table combines Inland Waterways & Ports into one line: $45B of needs and $32B of funded investment. Because that source does not split the two categories, this populated table uses a clearly identified 60% Inland Waterways / 40% Ports modeling split. State grades and allocation multipliers are also provisional model inputs.
National Infrastructure Amount: $5.41 Trillion •
ASCE Combined Inland Waterways + Ports Needs: $45B •
ASCE Combined Funded 2024-33: $32B •
Modeled Inland Waterways Amount: $19.20B •
Modeled B Target: $27.00B •
Modeled Additional Requirement: $7.80B
Variable Category-Specific Allocation Percentage:
Each state's Inland Waterways allocation is independently calculated from its Inland Waterways grade weight multiplied by an Inland-Waterways-specific network multiplier, then normalized to 100% of the modeled national Inland Waterways amount. The engine does not copy Transit, Rail, Ports, or Aviation percentages.
