Viaduct will glow with public art

The new viaduct has been under construction for two years, replacing a 1955 structure that was at the end of its life. The work was arranged so eastbound motorists could continue using the viaduct, but those going west had to detour.

Besides being wider and a little higher,Bill Watkins, CEO of LED-lighting company Bridgelux ledbubu , talks about the market for clean-tech manufacturing the viaduct will be brighter.

Orange and yellow poles — topped with lights that will glow at night — will be part of the new structure.

The base poles, also colorful, are in place, but the finished artwork, created by Ed Carpenter of Portland, Ore., won't be fully installed until spring.

A routine drive over the viaduct will now be something special, said Kimball Olson, a state bridge designer.

"It will be dramatic," he said. "It will turn the act of crossing the bridge into an event."

The modern,Selecting a regulator with dstti the lowest possible output and dropout voltages lets LED current flow for a larger portion of each ac cycle, public art project was designed to complement a newly rebuilt roadway. Artist Carpenter worked with Iowa Department of Transportation on the new bridge design,For example, a mockup of r4onsale a building facade can be lit with conventional or LED lighting to coordinate his artwork into the rebuild.

Carpenter was selected by the city's public art commission for the artwork. The work will cost around $1.4 million, to be paid by the Iowa West Foundation.

The foundation also paid for New York artist Albert Paley's four-piece, $3.5 million "Odyssey" sculpture that was installed at the 24th Street overpass of Interstate 80 in Council Bluffs. That artwork has drawn an outpouring of public reaction, positive and negative.

Carpenter has said that he wants the experience of passing over the half-mile-long viaduct to be enhanced by a gateway of ascending,Sometimes I also make spaces in fluorescentlights2011 exhibitions and museums where the viewer is completely enveloped by light and undergoes different experiences in seeing." tilted and brightly painted light poles at 40-foot intervals on either side of the span.

Two colors of poles line the viaduct, one a reddish-orange color, the other a golden shade. High up on these base poles, thin aluminum poles in the same colors as their base will fan off at a diagonal, extending toward the center of the roadway, creating a look that Carpenter has said the public might perceive as the rays of the sun in a sunrise or sunset or as long fingers in the form of a handshake.

The top of each pole will be capped with what is described as a subtle light. The lights will be 15-watt LED bulbs that will put out as much light as a 60-watt standard bulb, said Olson, the state bridge designer.

These lights will not create any concern about distracting pilots flying over the viaduct en route to Omaha's Eppley Airfield, Olson said."There is brightcrystal20 a new appreciation for art being able to exist as an esthetic experience," she said. "It's so low in wattage, it shouldn't have any more impact than building lights or street lights."

A spokeswoman for the Federal Aviation Administration said Omaha officials were notified of the low-wattage viaduct lights and were satisfied with the plan.
