RFP2021-02 - Crystal Valley Interchange - Planning & Design Services

The Town of Castle Rock (the “Town”) is interested in obtaining consulting services to advance the construction of an interchange at I-25 near the Town’s southern boundary limits, Crystal Valley Interchange (CVI), and the West Frontage Road relocations (Segment 1C and 1B). A Finding of No Significant Improvements (FONSI) was federally approved in 2005. Some preliminary engineering work has been completed that has allowed the Town to receive a Right-of-Way (ROW) plan set approval from CDOT, and the Town is currently in the process of acquiring the identified ROW. It is the Town’s intent to keep the interchange geometry within the identified ROW limits as much as practicable. The Town is a recipient of a BUILD Grant for preliminary engineering and ROW.
