Project Benefits:

This rural roadway provides important mobility to this region of Las Animas County and replacing the 85-year-old bridge will provide motorists with a stable and up to date structure with a 100-year design life, wider shoulders and smoother pavement. While working on this project, crews will also make safety improvements to this stretch of highway by replacing the existing guardrail and installing rumble strips and delineators.
