From The Record:
About 16,000 plastic zip ties hold thousands of knitted afghans, scarves, socks, hats and blankets to the cold concrete of the bridge. Some of the pieces arrived from as far away as Australia and New Zealand.
Volunteers helped Sturdy sew together all the knitted scarves to wrap around the arches, totalling nearly 830 metres. Between Tuesday and Friday, about 30 volunteers helped Sue attach the pieces to the bridge.
