Since its inception, and its renaming to the Border-to-Border trail in the 1990s, the project has expanded its scope and incorporated additional funding from public and private sources.

[3] When completed, the Border-to-Border Trail system will link Ypsilanti, Ann Arbor, Dexter, and Chelsea with off-street, non-motorized pathways for walking, bicycling, and other recreational activities.

The mid-2010s also brought additional private funding to the trail, with expansion plans for a segment from Dexter west to Chelsea.

[6] The total cost of constructing the trail was estimated at $30 million in 2019, with additional fundraising still under way to fund the entire project.

The B2B uses city streets through Chelsea, and heads due east, paralleling Dexter-Chelsea Road and the Michigan Line railroad tracks to Dexter.

[10] From Dexter east to Ann Arbor, the B2B follows Huron River Drive in a general southeasterly direction, connecting to Delhi Metropark.

Near the VA Hospital, the trail enters Gallup Park, and runs east to Geddes Dam at the Ann Arbor city limits.

[11][12] The B2B recrosses the Huron River twice at Geddes Dam and Dixboro Road, passing through the campus of Washtenaw Community College.
