Description

  • CTDOT inspects 5,513 roadway bridges, 1,823 of which are National Bridge Inventory (NBI) structures on the National Highway System (NHS).
  • 4,004 of these bridges are state maintained; the remaining 1,509 are maintained locally or under another jurisdiction.
  • 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:

Federal Requirements:
  • 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)
State Goal:
  • 95% or more of State-Maintained bridges in a SOGR (State target)

Asset Valuation

$15,850,000,000

Asset value is estimated using the replacement value. For bridges, replacement value is the product of deck area and unit construction cost. For 5,306 bridges:
37,734,498 sqft * $420/sqft = $15.9 billion.

Measures & Goals

CTDOT has set the following bridge condition goals:

Federal Requirements:
  • 10% or less Poor by deck area on NHS-NBI bridges (Federal minimum is less than 10% Poor)
  • 20% or more Good by deck area on NHS-NBI bridges
State Goal:
  • 95% or more of State-Maintained bridges in a SOGR (State target)
