The Colorado Department of Transportation (CDOT) released a list of four teams it has deemed qualified to compete to rebuild Interstate 70 in northeast Denver, based on responses to a request for qualifications the agency issued in March. At $1.2 billion, the P3 will be the state’s largest construction project to date.
The four teams are: 5280 Connectors, Kiewit/Meridiam Partners, Front Range Mobility Group and I-70 Mile High Partners.
The design-build-operate-finance-maintain project will involve adding a tolled express lane in each direction on I-70 from I-25 to I-225, removing a 50-year-old viaduct and lowering the interstate in that area and constructing a four-acre cover over a portion of the lowered highway.
“I-70 East is a critical artery for Colorado. We have the opportunity with this project to bring major improvements to this interstate and replace the aging I-70 East viaduct — the very last of the 30 worst bridges in the state not yet addressed,” said I-70 East Project Director Tony DeVito.
The project is expected to be funded through local, state and federal funding and private investment, such as debt in the form of Transportation Infrastructure Finance and Innovation Act loans or private activity bonds and equity investment.
An initial draft request for proposals will be issued this fall and CDOT expects to announce the winning bid next year.
The Final Environmental Impact Statement is due to be released early next year. Construction is scheduled to begin in 2017.
