Plum Creek Parkway
For drivers on the south side of Castle Rock, the Town is planning a phased project to widen Plum Creek Parkway between Gilbert Street on the west and Ridge Road on the east. In addition, the intersection of Plum Creek Parkway and Gilbert Street will be converted from the current temporary signal to a multi-lane roundabout. These improvements are expected to improve access to Plum Creek Parkway’s interchange with I-25 and increase bicycle access with new bike lanes.

Learn about the project
DesignCouncil approved a design contract with engineering firm Kimley Horn & Assoc. at its April 4, 2018, meeting.
In addition to reconstructing and widening Plum Creek Parkway, the project will include a new roundabout at the Gilbert Street intersection. Feedback to date has led to two enhancements being added to the project: a guardrail along part of the north side of the roadway, and installation of a pedestrian crossing with flashing lights. Additional design enhancements Town Council will consider on Sept. 18 are:
- Constructing an additional roundabout at Eaton Street
- Constructing a sound fence along both sides of the roadway
Timeline and phasing
Construction on the roundabout and phase one of the widening – between Gilbert Street and Eaton Circle – is anticipated to begin in fall/winter 2019, starting first with underground utility work. Construction in the roadway itself would begin in spring/summer 2020, following completion of the utility work, and is anticipated to wrap up by the end of that year. The second phase of construction (widening of Plum Creek from Eaton Street to North Ridge Road) is tentatively set for 2021, depending on prioritization of available funding.
Design for this project is budgeted at $480,515 and is funded by the Town’s Transportation Capital Fund, which includes growth-related revenues from impact fees and building use tax.
These improvements were defined in the Town’s Transportation Master Plan. Reducing congestion in the area has been a priority for Town Council. Learn more about that plan and read the document at CRgov.com/TMP.
