Pittsburghers will see the Rachel Carson Bridge (9th Street Bridge) shine on Comcast Light Up Night®, Friday November 18 and throughout the rest of the holiday season with a custom art installation that highlights Pittsburgh energy innovation, said Mayor William Peduto at a Downtown Pittsburgh Holiday Season media event this morning hosted by the Pittsburgh Downtown Partnership.

Mayor Peduto provided more details about Energy Flow, the temporary lighting installation on the bridge announced earlier this summer as part of the city’s year-long bicentennial celebration. Energy Flow is a collaboration between environmental artist Andrea Polli and Ron Gdovic of WindStax, a Pittsburgh-based wind turbine manufacturer. Energy Flow was selected by the Pittsburgh Bicentennial Steering Commission after a national call for bridge lighting ideas to celebrate the city’s bicentennial.

With financial support from Covestro, LLC and logistical support from Duquesne Light Company and Allegheny County, Energy Flow’s environmental art installation will debut to the public on the Rachel Carson Bridge during the 2016 Comcast Light Up Night® celebration on Friday, November 18 beginning at dusk.

“For a long time, the Sister Bridges have been a symbol to people far and wide of our city, county and region,” said Allegheny County Executive Rich Fitzgerald. “We’re excited to support the Pittsburgh 200 celebration by making the Rachel Carson Bridge available for this effort and look forward to seeing the final results of this unique collaboration.”

“Energy Flow is an appropriate tribute to the legacy of Rachel Carson, the Pittsburgh environmental pioneer for whom the 9th Street Bridge is named, and a tribute to this city of innovation,” said Mayor Peduto. “Ron and Andrea will create what’s called a ‘microgrid’ powered by wind to illuminate one of our iconic bridges with beautiful LED lights. It’s a perfect celebration of our historic past and our future as a leader in technology and culture. You won’t want to miss seeing it for yourself shining over the Allegheny River.”

Sixteen wind turbines specially designed for the project and a weather station that captures data about wind speed are being installed on the bridge this week. Strips of over 27,000 multicolored LED lights running up the bridge’s vertical cables will be installed as the next phase of the project.

“Covestro is proud to be part of the Bicentennial year events and to celebrate with the city we have called home for more than 60 years,” said Bob Walker, Covestro media representative. “This colorful lighting display and its use of renewable energy so perfectly capture our vision at Covestro – to create a cleaner, brighter future through innovative technologies. We’re proud to share that vision with the Pittsburgh region.”

The Pittsburgh Bicentennial Commission’s Bridge Committee was co-chaired by Jay Sukernek, Executive Vice President and Chief Financial Officer of Riverlife, and Jeremy Waldrup, President and CEO of the Pittsburgh Downtown Partnership. The committee spent months planning and working towards the ultimate goal of a bridge lighting for the Bicentennial Celebration. Comcast Light Up Night® is the Pittsburgh Downtown Partnership’s annual event that heralds the start of the holiday season and was a natural fit for debuting the Energy Flow special lighting installation.

“Comcast Light Up Night® showcases Pittsburgh at its best during the holiday season,” said Waldrup. “The lighting display on the Rachel Carson Bridge will be a can’t-miss addition to the exciting lineup of events and attractions in Downtown on November 18 and throughout the rest of the holiday season.”
