The major Colorado north-south interstate, I-25, runs through Castle Rock and links the community with the major east-west routes of I-70 and I-80. Three I-25 interchanges in town provide direct access to the town’s commercial districts as well as US Highway 85 and Colorado Highway 83 and 86. Two new I-25 interchanges are planned and an existing one is being reconfigured.
Castle Rock is completing final segments of a ring road that will support the free movement of future traffic around and through the community. Going counter clockwise from the northeast, the ring road is composed of Founders Parkway, Meadows Parkway, and an extension of Coachline road on the west side of I-25 to be named Plum Creek Parkway (new Southwest connector road), and an extension of Plum Creek Parkway on the east side of I-25 (new Southeast connector road). |
