The project is supposed to eventually double the length of the Greenway and extend to Naches.
The Greenway Foundation says paving and clearing one mile costs up to $350,000.
Walkers and joggers say they're happy with what's already been added.
"I like to walk and I like to ride my bike. And the more that's completed of it, the better, because I like to go more than just a mile," said pathway user Sandy Gavin.
You can help add onto the Greenway by donating $50, which helps fund a foot of pathway.
The Greenway Foundation says it has already raised over $140,000 from donations.
