The Willamette Light Brigade was founded in 1988 with a mission to enhance and beautify the city of Portland by lighting the bridges that span the Willamette River and therefore uniting the East and West sides of the city. Over the last four decades, Willamette Light Brigade volunteers have successfully advocated for and facilitated the lighting of many of Portland’s iconic bridges. The WLB continues to be part of long term planning for the bridges in the city of Portland.

In 2015, The Willamette Light Brigade founded the Portland Winter Light Festival in an effort to propel forward its mission of connecting community and enriching the public realm through artful lighting. The light-based art and technology event continues to be a beloved annual winter event that is presented for free to the public each February, and provides significant economic and cultural stimulation to Portland during the darkest time of year.
