Performance Projections
In order to achieve a SOGR an average of 755 light fixtures need to be replaced each year for approximately 10 years; replacements then drop to an average of 400 lighting fixtures per year to maintain a SOGR. Highway Safety Improvement Projects currently replace an average of 250 light fixtures per year, leaving the remainder to be installed by roadway lighting replacement projects. The preferred scenario includes approximately 755 light fixtures replaced through illumination specific projects and 250 light fixtures replaced through safety improvement projects.
Asset Valuation
$463,980,000
Asset value is estimated using an average replacement value per lighting system.
209 lighting systems * $2.22M each = $463.9 million
Measures & Goals
There are no Federal requirements for illumination at this time. CTDOT has set the following state goal:
- 90% of lighting systems in a SOGR

Light Fixture Performance Projections
In this chart:
- Projections based on funding as of 12/31/23
NOTE: "Current Funding" shown in the graphs is limited to funding programed to address State of Good Repair. Projected performance is expected to be greater due to asset improvements funded through CTDOT's Capital Program which are not captured. The Department will soon be able to capture this funding through a project asset data system in development.
