Bridger Bowl & Crosscut Trails 2025

In partnership with Bridger Bowl and Crosscut, The Dirt concern and SWMMBA are excited to announce the development of 7 miles of purpose built mountain bike trails in our own backyard!

Over the past year, we've collaborated with land managers, walked the terrain, and designed a trail proposal that will bring new biking opportunities to Bozeman. 

Our goal is to hire 1-2 professional trail builders to create two distinct flow trails, forming a new loop for the Bozeman community. One will be an easy, multi-directional trail ideal for climbing, and the other a moderate downhill flow trail with progressive features.

As of December 20, 2024 the RFP is open for bidding (see bottom of this page) through January 31, 2025. With hopes that phase 1 of this project will begin in the spring of 2025 and that these new trails could be ridden for the first time October of 2025, weather permitting.


Help Us Build New Trails in Bozeman!

The estimated cost for this project is $300,000, and we need your help to make it happen. Every donation, no matter the size, brings us closer to expanding our local trail network!

As we receive bids from local builders—many of whom have crafted beloved trails at Big Sky, Marshall Mountain, and Legacy Bike Park—we'll update you with transparent cost details and progress reports.

Thank you for helping bring new trails to Bozeman. We look forward to riding with you soon!

REQUEST FOR PROPOSAL

Proposals may be submitted through January 31, 2025 to TDC Vice President Drew at drew.m@southwestmontanamba.org.

  • 1.1. Background:

    The Dirt Concern (TDC) and the Southwest Montana Mountain Bike Association (SWMMBA) are excited to present this proposal for partnership with Bridger Bowl Ski Area and Crosscut Mountain Sports Center. Both resorts have long been pillars of the Bozeman community, each boasting a rich history of over 50 years in promoting outdoor recreation, health, and wellness. Bridger Bowl, founded in 1955, has become synonymous with winter sports and community engagement, while Crosscut, established in the early 2000s, has fostered a love for Nordic skiing and year-round outdoor activities.

    Both resorts not only provide world-class recreational opportunities but also inspire healthy, lifelong habits among residents and visitors alike. They have cultivated a vibrant community centered around outdoor activities, encouraging individuals and families to embrace an active lifestyle. Their commitment to sustainability and environmental stewardship aligns closely with the values of TDC and SWMMBA, whose mission is to create and maintain accessible, sustainable mountain biking trails that enhance community health and well-being.

    Our vision for this partnership is to develop purpose-built trails that cater to diverse skill levels and promote inclusivity in the sport by establishing a network of mountain biking trails near Bozeman that feature well-designed berms, directional trails, and bike-specific features, all tailored to match the requests included in the feedback gathered from the Bozeman community through a survey conducted by The Dirt Concern in 2023.  Phase one of this project includes roughly 7.25 miles of new purpose-built mountain bike trail, broken out into 3 specific segments.  The first segment is approximately one mile in length and will be built via collaboration between Crosscut and The Dirt Concern’s volunteer workers.  The other two segments, totaling approximately 6.25 miles, will be designed and constructed by one or two professional trail builders.

    By joining forces with Bridger Bowl and Crosscut, we aim to create a dynamic outdoor recreation space that not only complements the existing offerings of both resorts but also enriches the lives of community members. Together, we can ensure that Bozeman remains a vibrant hub for outdoor enthusiasts, fostering a deep appreciation for nature and promoting healthy lifestyles for generations to come. We look forward to collaborating on this project and contributing to the ongoing legacy of outdoor adventure in our community.


    1.2. Purpose of the RFP:

    The purpose of this request for proposals is to solicit two (2) separate bids from contractors interested in designing and building approximately 6.25 miles of new mountain trail.  One trail, Gryffindor, will be a bike-optimized, two-directional multi-use trail.  The other, Slytherin, will be a bike specific downhill-only flow trail from the northwest corner of Bridger’s property down to Crosscut’s main parking lot. 

    1.3. Project Overview:

    The project’s primary purpose is to design two different, but connected trails that span Crosscut and Bridger’s private property.  The first trail will be bike optimized, multi-directional, and multi-use, and will start at Crosscut’s D Lot and end at the Northwest corner of Bridger’s property above the Alpine cabin.  The second trail will be a bike-only, downhill flow trail between the top of the first trail, leading back to Crosscut’s main parking lot. This loop will create the perimeter of what will eventually be several additional interior trails of varying length, style, and difficulty.

    1.4. Submission Deadline:

    Proposals must be submitted to TDC by January 31, 2025.

  • 2.1. Trail Design & Construction:

    Trail segments

    This procurement effort includes two (2) trail segments from the attached appendix A.  Each trail segment should receive a separate quote.  We will consider combined quotes, but require each segment to be broken out into independent outlines.  

    1. Gryffindor - 17,000’ - 17,500’, 3.25 mi, 5.8% average grade.  The corridor starts at Crosscut’s D Parking Lot, climbing above Bridger’s summer access road, and ending above the Alpine cabin.  There are multiple areas to establish rest stops or picnic areas on the way up.  This will be a multi-directional route primarily used for climbing to the top of the Slytherin Trail.

    2. Slytherin - 15,000’ - 16,000’, 3 mi, 6.5% average grade.  A downhill only intermediate flow trail.  This trail should include several progressive features, but all must be rollable or easily bypassed.

    Seasonal considerations:

    None of these segments are flagged. Design and flagging should be planned for as soon as the upper elevations of the project site are accessible following snow-melt, which typically occurs by early-June. The construction window for this project area is typically from mid-June through mid-October. Typically, the higher elevations in this zone have gotten their first snowfall by early October and can be expected to be under snow by the end of October.

    Creek crossings and wetlands:

    While there are no creek crossing for the proposed lines, there may be intermediate wetlands or damp areas that need to be addressed. Proposals should include in the cost estimate no more than TWO trail bridges (between 8 and 12 feet long).  It is entirely possible neither route will require any built structures.

    Desired trail style:

    The desired nature of the new trails is “traditional, bike-optimized singletrack” for Gryffindor, and “bike specific, downhill flow trail” for Slytherin.  Gryffindor should be a green multi-directional trail with clear sight lines, large turns, and be accessible to most bikers.  Slytherin should be a blue flow trail with a few progressive features that is accessible to intermediate and advanced mountain bikers in the Bozeman area.  While mountain bikers make up the primary user group, Gryffindor will still be available to hikers, trail runners, and berry pickers.  Existing trails in the area have average grades significantly greater than 8%. We desire the new trails to offer a more intermediate friendly climbing experience, with average grades of less than 7% wherever possible on the uphill.

    Trail system connectivity:

    Existing trails surround the proposed routes.  Crosscut has several trails, such as What Goes Up and Must Come Down that we want to provide connectivity to.  Similarly, just off Bridger Bowl’s private property exist several USFS trails that should be considered.  It is the desire of TDC to not only maintain connection between these trail zones, but to improve access by providing a better experience than what’s currently available. That means building them to modern standards, with a bike optimized character, and with two-way traffic in mind ( Gryffindor) and downhill, progressive features in a driving characteristic (Slytherin).  Crosscut will continue building out their summer trail system.  If this project goes well, there will be a phase 2 and 3, where additional trails are added to Bridger and Crosscut’s private property.  See the broader trail proposal for more detail on phase 2 and 3.

    2.2. Environmental Considerations:

    The project lies entirely on private property. Given the project will disturb more than one acre of soil, the contractor will be required to work with the land owners (Crosscut and Bridger Bowl) to determine if environmental permitting is required, and if so, drive that process. Permits such as a Stormwater Pollution Prevention Plan (SWPPP) may be required.

    2.3. Safety Standards:

    Trail design and construction should follow safety standards as laid out in leading trails design handbooks such as IMBA’s Trail Solutions and the Guidelines for a Quality Trail Experience. The trails are to be designed and built as “intermediate bike-optimized singletrack shared-use nonmotorized trails” and “Bike specific downhill flow trail”. While we are comfortable with the types of features typical of intermediate mountain bike trails, such as rollers, side hits, optional jumps, rock rolls, and so on, the new trails need not include any unnecessary built features and should require minimal borrow-pit style construction. Gryffindor should make use of the natural terrain features, with elevated turns built for rideability both uphill and downhill, but not necessarily for maximum speed by downhill riders. The “switchberm” style of elevated

    turn is most appropriate along Gryffindor. Slytherin (downhill-only) should incorporate larger berms, rollers, and table-top jumps designed for downhill riders to maintain speed and get some air where possible.

    2.4. Project Timeline:

    December 20th, 2024: TDC posts RFP

    January 31st, 2025: Proposals due

    February 1st – 27th, 2025: Proposal evaluation

    February 28th, 2025: Contract finalization and award

    March 1st – May 31st, 2025: Pre-construction phase / permitting (SWPPP, etc. as needed)

    June 1st – June 7th, 2025: Contractor mobilization, design, and flagging.

    June 7th – September 1st, 2025: Construction period, with work substantially completed by September 1st*

    No later than September 10th: Initial inspection with TDC, Crosscut, and Bridger.

    September 10th - October 15th: Final adjustments to trail based on inspection results.

    October 1st, 2024: Final inspections with TDC, Bridger, and Crosscut. Trail ready to open (as conditions allow).

    *Ideally, contractors will be flexible and able to mobilize based on actual spring snow conditions. Should Bridger and Crosscut have a low snow year, it will be possible to access the site for flagging and construction earlier than noted above. In the case of a heavy snow year it could be later in June before the upper elevations are accessible.

  • Appendix A:


    Glossary:

    • TDC - The Dirt Concern. This is the local mountain bike trail association and a regional chapter of SWMMBA.  Their service area stretches from Gallatin Canyon, up and over Hyalite towards the Paradise Valley, and north to the northern Bridgers.  Their role is to engage with the local community and drive projects, events, education, and trail advocacy in the Bozeman area.

    • SWMMBA - Southwest Montana Mountain Bike Association.  This is the parent organization of The Dirt Concern.  Their service area stretches from Big Timber to the Idaho border, and north up towards Helena.  They manage the legal side of operating a trail association, from managing funds to maintaining the non-profit status.

    • Bridger Bowl - Bozeman’s local ski area.  They are one of the two primary land managers in this project.  They own roughly 600 acres of private land that borders Crosscut and USFS land.

    • Crosscut Mountain Sports Center - Bozeman’s local nordic ski area.  They are the other primary land manager in this project, and own roughly 600 acres of private land that borders Bridger Bowl and USFS land.

    • USFS - United States Forest Service.  Bridger Bowl and Crosscut’s property border Custer Gallatin National Forest.  While none of this project is on USFS land, they will likely be involved or considered in some capacity.
