Mill Creek Triangle Trail

About the Mill Creek Triangle Trail

Tri-State Trails is leading the Mill Creek Triangle Trail Feasibility Study, a multi-jurisdictional effort to develop a 40+ mile regional trail network in central and northern Hamilton County. The vision for the Mill Creek Triangle Trail is to create an equitable transportation and recreation amenity that connects residential neighborhoods to the Mill Creek; to local business districts and key destinations; to Great Parks’ regional greenspaces like Winton Woods, Glenwood Gardens, and Sharon Woods; and to the planned CROWN 34-mile trail loop in Cincinnati.

In August 2025, all seventeen project partners formally adopted the Mill Creek Triangle Trail Feasibility Study, marking a major milestone for the project. While adoption does not mean the trail will be built overnight, it represents a critical step toward implementation. With a shared, locally endorsed vision in place, partners are now better positioned to pursue funding, prioritize key corridors, and take the coordinated actions needed to bring this 40+ mile regional trail network to life.

Tri-State Trails continues to work closely with communities and key stakeholders along the Mill Creek Triangle Trail corridor to advance next steps toward implementation. This includes coordinating on priority trail segments, refining trail alignments, and pursuing grant funding opportunities to begin building the trail and move projects from planning into action.

Vision Statement

The Mill Creek Triangle Trail will create a safe and accessible 40+ mile shared use trail network in Central Hamilton County, ultimately linking to the regional trail network. By uniting twelve communities, the Triangle Trail will provide an equitable transportation and recreation amenity that reconnects residents to the natural environment of the Mill Creek watershed and encourages more active, healthier lifestyles. Through collaboration and partnerships, the Triangle Trail will be a well-maintained, highly utilized socio-economic catalyst that fosters a sense of wellbeing and community pride.

Feasibility Study Planning Process

This study emerged from years of collaborative efforts between local governments and nonprofit partners to improve active transportation in Hamilton County. Starting in 2009, the Connecting Active Communities Coalition was formed, followed by Tri-State Trails’ creation in 2012 and the first Regional Trails Plan in 2014. The Mill Creek Collaborative was established in 2015 to begin planning the Mill Creek Triangle trail network. Key milestones, such as funding for the Glenwood Gardens to Winton Woods Trail in 2021 and Great Parks land acquisition in 2022, propelled this study forward.

In 2023, Tri-State Trails and the Mill Creek Alliance launched a fundraising campaign to support the study. With contributions from more than a dozen local government and community partners, a Steering Committee was formed in October 2023 to guide the effort with the following objectives:

Develop a safe and connected walking and biking network in the center of Hamilton County for all ages and abilities
Improve access to schools, parks, business districts, and other key destinations
Explore multiple trail alignment options and recommend a preferred route
Prepare detailed cost estimates for the preferred trail route and alternatives
Conduct public engagement to gather input and support for the proposed routes
Position priority segments for future state and federal funding for future construction

The study assessed existing conditions across the corridor, including current and planned trail infrastructure, community assets, and demographic data. Throughout early 2024, the project team worked with local staff through corridor-based working groups to develop and refine potential trail alignments.

Public input played a key role in shaping the recommendations. Engagement began 30 days before the May 1, 2024 Public Open House at the Sharon Centre and included a 45-day Virtual Open House with an interactive survey. Outreach efforts also included a project website, social media, newsletters, yard signs, fliers, and participation in community events, providing multiple ways for residents to learn about the project and share feedback.

The feasibility study was finalized in early 2025 and presented to each participating community. By August 2025, all project partners formally adopted the study through resolutions or letters of support, establishing a shared vision for advancing the Mill Creek Triangle Trail.
