Major Achievements

Build 6.5 miles of median widening, temp bridges & drainage within 7 months to help achieve overall goal of completing entire package in 3 years.

Savings

Although not the final product team decided to temporarily build the median to give CDOT enough time to acquire ROW and move utilities. Was able to leave 90% of median paving in place as permanent paving. It saved CDOT millions by keeping to an overall schedule.
