Description

  • CTDOT is responsible for maintaining approximately 1,596 overhead sign supports on state maintained roadways
  • Sign supports are made up of three categories:
    • 673 Cantilevers

Performance Projections

Sign support projections use deterioration curves for the overall structure condition rating. These curves are based on the assigned 34-year service life of sign supports.

Asset Valuation

$289,845,000

Asset value is estimated using the replacement value. For sign supports, replacement value is based on the average unit construction cost by type:
Cantilever
$150,000 * 673 = $100,950,000
Full Span
$285,000 * 614 = $174,990,000
Bridge Mount
$45,000 * 309 = $13,905,000

Note: This value does not include the cost of the sign panels.

Measures & Targets

There are no Federal requirements at this time. CTDOT has set the following sign support condition goal:

  • 90% or more of sign supports in a SOGR
