We’ve put up the final installment of our project-wide FLOW art. While we’re sad to see the end of our last FLOW art collaboration, we’re so excited to showcase the incredible talents of yet another group of local artists - Gia Valente (in Wallingford), Amaranta Ibarra (in Fremont), and James Lilly (in Ballard). Take a drive down to the project and check them out!

Thank you to all our FLOW artists who have shared their work with us and the community. Your art has been a source of beauty and inspiration at our construction sites.

Learn more about these artists and all the art  showcased along the Ship Canal Water Quality Project on our website’s Public Art page.
