Confluence Area Multi-Use Path Projects
Next Steps for the Airport-Andrus Path project:
Spring 2019 -
The project team is working to finalize the engineering and design of the multi-use path. A graphic depicting the final alignment can be found here.
Advance utility line relocation work will take place.
Late Fall 2019
Project construction will begin and is anticipated to take six months.
Confluence Area Multi-Use Paths
Three multimodal connections between Gunbarrel and Boulder have been identified in the area of the confluence of Boulder Creek and South Boulder Creek and Boulder Creek and Fourmile Canyon Creek (Confluence Area):
- Andrus Road to Airport Road Multi-Use Path Project
- Valmont Road Multi-Use Path (61st Street to the South Boulder Creek Trail along an RTD rail alignment north of Valmont Road)
- 61st Street Multi-Use Path, Andrus Project to Valmont Road
These missing links, identified since the 1980s in the City of Boulder’s Transportation Master Plan (TMP), will provide improved bicycling and pedestrian facilities for residents, employees and visitors to the city.
Additionally, the project improvements support the following TMP goals:
- Creating travel options through construction of multimodal facilities
- Supporting regional travel
The first project to be constructed will be the Andrus Road to Airport Road Multi-Use Path project.

The Andrus Road to Airport Road Multi-Use Path project is one of three City of Boulder transportation connections identified in the area of the confluence of Boulder Creek and South Boulder Creek and Boulder Creek and Fourmile Canyon Creek (Confluence Area), which will provide a much-needed multimodal connection between Gunbarrel and the city.
The Andrus to Airport Path project will construct a 10-foot-wide, off-street, concrete multi-use path between Andrus Road and the Airport Road office park. The project will link to the existing 63rd Street multi-use path at the underpass on 63rd Street and improve the city’s system of multi-use paths, regional bicycling travel, and off-street and multi-use path connectivity between Gunbarrel and the Boulder urban center.
The proposed conceptual project design was created through the collaboration of the city‘s Public Works and Open Space and Mountain Parks departments and between the city and Boulder County. The edges of the proposed path are a solid pink line, the centerline of the path is a dashed yellow line, the proposed fence is in red and the existing fence is in orange.
The Andrus Road to Airport Road Multi-Use Path project will provide the following improvements:
- Construction of a new 10-foot, concrete multi-use path
- Installation of fence to separate the new commuter bikeway from livestock that grazes on adjacent Open Space and Mountain parks land
- Construction of an at-grade crossing at 61st Street along the proposed path alignment
- Construction of a pedestrian/bicycle bridge over Fourmile Canyon Creek along the proposed path alignment
A similar multi-use path project which installed fence was constructed near 48th Street and Arapahoe Avenue. These photos provide an example of what the Andrus Road to Airport Road Multi-Use Path project will look like when complete:
Planning and design began in fall 2015 and will be completed in 2019.
Construction is estimated to begin in late 2019 and will take about six months to complete, depending on weather conditions, contractor schedules and materials delivery.
The project budget is approximately $1.4 million and is funded with city transportation funds and a Colorado Parks and Wildlife 2019 non-motorized trails grant.
Previous Public Outreach
In April and May 2016, the project team met with adjacent property owners to discuss project improvements .
The project land use application was reviewed and conditionally approved by the Boulder County Commissioners at their Tuesday, Nov. 1, 2016, meeting.
The project was featured at the Boulder Valley Comprehensive Plan Future Choices Forum for Gunbarrel held on Monday, Jan. 9, 2017.
The project was presented as part of a staff update to the Open Space Board of Trustees at their Wednesday, April 12, 2017, meeting.
An information session was held on May 23, 2018 to present information on multi-use paths, projects and programs from Open Space and Mountain Parks, Transportation and Water Utilities, plus Boulder County Transportation, including:
- Confluence Area paths
- Open Space and Mountain Parks' completion of Boulder Creek Restoration work and their plans for additional work along lower Boulder Creek
- City Water Utilities Division's evaluation of alternatives for the realignment of the city’s main wastewater interceptor sewer
- Information on Boulder County Transportation projects in the Confluence Area, primarily the RTD Rail Trail Master Plan that will assess the feasibility and alignment options for a soft-surface trail along RTD’s railroad right-of-way that crosses 61 st Street just north of Valmont Road, and potential future traffic and bicycle safety improvements to the Valmont Road and 61 st Street intersection
