El Paso County’s transportation network consists of more than 2,200 centerline miles of public roadway, ranging from major thoroughfares in urban areas to rural gravel roads and neighborhood streets and cul-de-sacs.
El Paso County Department of Public Works maintains over 1,170 centerline miles of paved roads, which equates to over 2,385 lane miles. 223 of the 1,100 centerline miles are chip sealed. Centerline miles include both sides of the road, whereas lane miles are the individual lanes (2 or 4 lanes depending on the road).
In 2023, a consultant surveyed the roads, and data was collected and analyzed on 2,221 centerline miles of pavement. This includes both paved roadways and gravel roads.
Information gathered included the pavement thicknesses, existing asphalt crack data and the pavement condition index (PCI).
The Pavement Condition Index (PCI) provides a numerical rating for the condition of road segments within the road network, where 0 is the worst possible condition (impassable), and 100 is the best (perfect condition).
The PCI tells public works officials the current condition of a road and the anticipated rate of deterioration of that road over time. The PCI values are used in prioritizing, funding, and executing maintenance and rehabilitation programs.
In order to determine the health or condition of the streets, the Pavement Condition Index (PCI) is used. The PCI is a 0-100 rating scale based on the physical and structural condition of a road:
- PCI scores of 70 to 100 are considered “satisfactory or good”. These are newly built or resurfaced roads that show little or no distress.
- PCI scores 50 to 69 are considered “fair” with only slight to moderate distress, requiring primarily preventative maintenance.
- PCI scores 25 to 49 are considered “poor” and are worn to where restoration may be needed to prevent further deterioration.
- PCI scores 0 to 24 are considered “serious” and may require full reconstruction.
