The Broadway Bridge in Portland will turn 100 next month and volunteers have come up with a creative way to honor it: YARN BOMBING!
The bridge is the longest rail-type Bascule bridge still in existence. It spans 1,742 feet (571 meters) over the Willamette River, in Portland, Oregon. Organizers hope to cover one whole side with their knit and crochet handiwork. So far, 150 volunteers have helped create a yarn banner shown above; it’s already the city’s largest knitted art installation in history.
The project will end with a block party on August 10, to celebrate the 100th Birthday of the Broadway Bridge.
CONFESSIONS OF A YARN-A-HOLIC 
Wow, i’ve seen some impressive yarn bombing but that actually looks a bit dangerous to have put up. Impressive!!
