- CTDOT defines a bridge as a crossing of at least six feet in length, including culverts. The Federal Highway Administration (FHWA) defines an NBI bridge as a structure measuring more than 20 feet in length.
- CTDOT has a distinct Major Bridge Program for large or expensive-to-replace bridges. 60 structures are currently categorized as Major Bridges.
State of Good
Repair (SOGR)
A bridge for which the condition rating for each of the three major components for a span bridge (Substructure, Deck, and Superstructure) or the structural condition of a culvert is rated at least a 5 on a 0-9 condition scale is classified as being in a SOGR.
Bridge Age
The average NHS-NBI bridge in Connecticut is 55 years old, which is 9 years older than the national average of 46 years. The state has a higher percentage of Poor bridges (by deck area) compared to the national average.

Performance Projections
The chart on the right depicts bridge condition for various funding scenarios. These were developed through an analysis program using CTDOT bridge condition data, as of Q1 CY 2024.
Asset Valuation
$17,222,364,000
Asset value is estimated using the replacement value. For bridges, replacement value is the product of deck area and unit construction cost. For 4,004 bridges:
34,444,728 sqft * $500/sqft = $17.2 billion.
Measures & Goals
CTDOT has set the following bridge condition goals:
- 10% or less Poor by deck area on NHS-NBI bridges (Federal minimum is less than 10% Poor)
- 15% or more Good by deck area on NHS-NBI bridges (Percent Good is established by each state; no Federal minimum for this goal)
- 95% or more of State-Maintained bridges in a SOGR (State target)
