National Bridge Inventory: Illinois 2020 - 2024
The state has identified needed repairs on 4,154 bridges.
This compares to 4,083 bridges that needed work in 2020.
Over the life of the IIJA, Illinois will receive a total of $1.5 billion in bridge formula funds, which will help make needed repairs.
Illinois currently has access to $891.8 million of that total, and has committed $438.7 million towards 104 projects as of June 2024.
Of the 26,928 bridges in the state, 2,517, or 9.3 percent, are classified as structurally deficient. This means one of the key elements is in poor or worse condition.
This is up from 2,374 bridges classified as structurally deficient in 2020.
The deck area of structurally deficient bridges accounts for 11.4 percent of total deck area on all structures.
