I-25 North Design-Build

Shannon & Wilson was the geotechnical engineer of record for CDOT, providing recommendations for steepened slope embankments (supported by geotextile reinforcement), foundation design for the bridge and culvert structures, and pavement design for more than 10 miles of interstate pavement.

This included new flexible pavement in the widening areas and rehabilitation of the existing pavement that will extend the service life an additional 20 years.  To complete the field investigation, we completed more than 100 geotechnical and pavement borings over three weeks of night mobilization using multiple rigs and field crews.
