Schedule & Funding
Preliminary design is anticipated to be complete in January of 2020, with final
design to be determined based on construction funding. Environmental clearance under the National Environmental
Policy Act, which is required before the project can be constructed, is anticipated in late 2020.
The I-25/I-80 interchange replacement is anticipated to cost approximately $110 million. This cost will be refined as design of the interchange progresses. While no construction funding is currently included in the 2019 State Transportation Improvement Program, WYDOT is actively engaged in identifying potential funding sources and partners to construct the project.
