Bloor Viaduct 'Luminous Veil' to light up Saturday night

The Bloor Viaduct will be aglow with colour on Saturday night, as 35,000 LED lights illuminate the bridge and its "Luminous Veil" for a Pan Am Games celebration.

Lighting the veil — a series of slanting steel rods that work as a suicide barrier — has been more than 20 years in the works. Now, the Pan Am Games and Danforth Business Improvement Area have finally provided the final push, as well as some $2.8 million in funding, to make it happen.

"The bridge is going to be alive," said Jennifer Jones, of the Danforth BIA.

Recent testing provided a sneak peek for some passersby, but the big show will go ahead on Saturday night.

Dereck Revington, the architect who designed the structure, has created a five-minute unveiling overture of light moving across the veil. The show will also include the flags from all 41 Pan Am countries and an appearance by the Games' torch.

"From my perspective it's absolutely exquisite," Revington told CBC Radio's Metro Morning.

The bridge lighting will begin as the sun goes down on Saturday. Jones said there will be plenty to do during the wait, with a rib festival on the Danforth side of the Don Valley and food trucks on the other.
