Yes.

The percentage of state roads in Colorado rated “poor” by the Federal Highway Administration has risen from 8% to 24% since the agency began collecting data in 1994, two years after the Taxpayer’s Bill of Rights became law.
The agency considers a road to be in poor condition if it has more than 14 feet, 2 inches, of roughness — like potholes — per mile. Only 34% of Colorado’s roads are in good condition, compared with the national average of 45%.
The American Society of Civil Engineers found Colorado drivers spend an extra $831 annually on car maintenance due to rough roads.
TABOR is a voter-approved constitutional amendment that limits how much tax revenue Colorado can collect and spend. Colorado’s gas tax, which funds much of the state’s $1.55 billion transportation budget — 48% of which goes to pavement maintenance annually — hasn’t changed since 1991 partly due to TABOR restrictions.
