Project Costs
Estimated costs to build near-term improvements on Segment 6 range from $228 million to $317 million. This cost estimate used 2015 dollars and is for building two general-purpose lanes and one tolled Express Lane in each direction. Actual project costs are subject to market conditions, such as the value of property acquisitions, material costs, and labor costs at the time the project goes to advertisement.
Project Schedule
The design plans for the ultimate build-out of Segment 6, which includes three-general purpose lanes and one tolled Express Lane in each direction, are currently five percent complete. The Final Environmental Impact Statement for this project was completed in 2011; however, no Record of Decision has been signed for this segment. The project team will continue to advance the design plans to prepare for future funding opportunities and to support the phased implementation of the I-25 North Corridor.
