New approach to roadway bridge lighting
New lighting system of Perley Bridge, which spans Ottawa River linking Hawkesbury, Ont, to Grenville, Que, uses twenty-nine 250-w mercury lamps, housed behind IES Type III glassware and mounted on 20-ft poles 88 ft on center; bridge roadway consists of two narrow lanes making location and mounting of poles as well as pole design itself crucial questions to be solved; poles were kept off roadway entirely by mounting them on angle brackets welded to I-beams on outer edge of bridge.
