HOW TO DESIGN AND MAINTAIN BRIDGE LIGHTING

This article provides some basic guidelines in the design of bridge lighting. The guidelines relate to visibility, selection of poles and lamps, floodlighting, and minimizing glare. Visibility of drivers is the first and most important goal. The equipment selected should be sturdy, having been designed and tested for use under severe vibration and in corrosive atmospheres. Poles are chosen with local wind conditions in mind. High-pressure sodium (HPS) lamps are excellent for bridge lighting as they are energy efficient and provide the most light for each watt of electricity. Maintenance is simplified if lighting components are standard and off-the-shelf. Floodlighting must be placed on rigid structural supports in locations readily accessible with standard maintenance equipment. A common technique in bridge floodlighting is to recreate the daytime effect of light and shadow. Glare can be minimized by using narrow beam floodlights and aiming them on-site. A glare shield reduces stray light even more.
