The Treeline stretches 3 miles from the B2B Trail and Broadway Park West to the Big House.

Defined by three segments, the Gateway, the Neighborhood, and Wolverine Way, the Treeline serves pedestrians, cyclists, neighbors and visitors alike.

The Treeline isn't just a path — it's a living connection between neighborhoods, generations, and experiences. This green corridor breaks down barriers between university and town, between north and south, between our river and our downtown. Every completed segment strengthens the fabric of our community, creating new opportunities for chance encounters, shared experiences, and collective memory-making.

The Gateway

A Signature Connection Taking Shape
The Treeline Conservancy is currently focused on bringing the Gateway to life — our most ambitious segment that will transform how Ann Arbor residents and students connect to the Huron River, and how county-wide community members access downtown Ann Arbor. This iconic pedestrian and cycling route will feature a signature bridge spanning North Main Street, creating a seamless link between the riverfront, campus, and the heart of our city.

The Gateway addresses a critical gap in Ann Arbor's infrastructure for people walking and biking. On a daily basis, nearly 30,000 cars flow into Ann Arbor via the M14/N. Main corridor and analysis from PeopleForBikes identifies this area as one of high cycling stress, where high-volume motor vehicle traffic creates challenging conditions for both cyclists and pedestrians.  

‍

This transformative segment will turn that barrier into an inviting, low-stress route for everyone — connecting the regional B2B Trail system directly to downtown while finally bringing the Huron River back into our city's daily life and linking Broadway Park West with surrounding neighborhoods.

Recent Progress:
‍

  • September 2025: Ann Arbor City Council unanimously authorized a jointly sponsored Request for Proposal to engage an engineering firm for design development
  • October 2025: State of Michigan awarded a $1 million grant to support the Gateway's design and engineering plans

‍

The Treeline Conservancy is working closely with City administrators to publish the RFP and has launched a fundraising campaign to raise the remaining funds necessary to engage an engineering firm. Your donation will help make this next step possible!


When completed, the Gateway Bridge will not only be a beautiful addition to Ann Arbor's landscape — it will be a game-changer for safe, accessible connectivity across our city.
