Lights. Camera. Bridges.

Allegheny County on Wednesday demonstrated an enhanced lighting system being installed on the Roberto Clemente (Sixth Street), Andy Warhol (Seventh Street), and Rachel Carson (Ninth Street) Bridges. They’re commonly referred to as the Sister Bridges.

The installation of 601,440 color LED lights across the three bridges that connect Downtown to the North Shore began this fall with the Rachel Carson Bridge.

The new enhanced lighting system includes 2,628 feet of linear video fixtures on the bridges’ suspenders, 192 rounded fixtures on the suspension chain pins (or eyebars), 132 spotlight fixtures on the towers and piers, and 12 custom replica fixtures atop the pylons.

Check out the lights.
