Big Dam Bridge

Lighting Designer: John Rogers, John Rogers Design

Supplier: Illumivision

Wireless Solution Sweden AB and Illumivision, Inc. recently turned the Murray Lock and Dam Bridge

in Little Rock, Arkansas into a spectacular tourist attraction. The newly constructed pedestrian and

bicycle bridge over Murray Lock and Dam, dubbed the “Big Dam Bridge,” recently held a special

ceremony to show off its new look, bejeweled with colored lights.

Illumivision, Inc. of Edmonton, Alberta worked in conjunction with lighting designer John Rogers of

John Rogers Design in Little Rock Arkansas during the design and installation of the bridge lighting.

169 Illumivision xtures are installed at the base of the 13 piers across the span of the dam. The

xture is an IP66-rated wall-washing LED that generates color-changing effects, perfectly suited for

the application.

Derek Pogany of Illumivision explained, “Originally the lighting for the bridge was to be designed with

1000W metal halide lamps with blue dichroic lters. A mock up was completed in the fall of 2004 by

Illumivision to demonstrate the effect and benets of LED lighting. The Light Wave xture, 84W and

108W RGB xtures give the exibility to control color-changing effects, which makes the overall effect

that much more dynamic.”

The challenge was to provide DMX to 13 piers along the span of the bridge. The only practical solution

was to use Wireless DMX. Pogany explained, “There was no question about choosing W-DMX™ by

Wireless Solution for this install. It had to have an IP65 rating and operate without any interference.”

One W-DMX™ transmitter with 100’ antenna cable, RF booster and a 14dBi antenna sent signal to

13 W-DMX™ receivers with 26’ antenna cables and a 2dBi antenna installed on every pier, each with

a receiving antenna that feeds to an enclosure with 24 VDC power supplies and three-output DMX

splitters. The distance is 300’ from the transmitter to rst pier antenna, and 70’ between each pier.

Pogany said, “Since the moment the lights turned on at the opening ceremony, we haven’t had a

single problem, and everyone is thrilled with the results. The lighting makes the bridge a spectacular

sight and a special attraction for the city of Little Rock.”
