- .' - :w 'Longest Brid , mi Aspiration of New low - level lighting on San Mateo - Hpyward Bridge Safety, Economy Lighting Design By LUIS BATIZA Senior Electrical Engineer Public safety, convenience and economy were the primary considerations in the design of the electrical and mechanical system for ihe San Mateo - Hayward Bridge. A major feature is the low - mouflted continuous lighting, ex - lending the entire length of the bridge. Other features of the electrical and mechanical de - I sign for the bridge are an ultramodern, high - voltage power system and a computer type control system. Low mounted fluorescent fix tures are placed end - to - end on the median barrier in the center of the roadway. The lighting fixtures will provide uniform ruad surface brightness and a pleas ant appearance, superior to conventional lighting. The panoramic view from the bridge is preserved because no vertical poles project above bridge railings. Before the light ing was installed, the system was studied and tested by the Institute of Transportation and Traffic Engineering of the Un iversity of California. Electrical power is furnished to substations on the bridge from PG&E sources, in flan Ma teo and Hayward. The power system is designed for utmostj iiiiiiniimiiiHiiiiiiiiiiiiiiiiMiiiiiiiiHiMiiiiiiiiMiMiriiiiiiiiMiiiiiiiiiiiiiMiiiiiiiiiitiiiiiiiiiiiiiiiiiiiiiiiiiiiiimii Bridge to Profoundly Affect Future Foley To the Editor: We are delighted to hear that the San Mateo Times is planning to publish, a special section to commemorate the completion oJ the San Ma - teo - Hayward Bridge. The new San Mateo - Hayward Bridge is one of eight toll bridges in California, with a ninth under construction over San Diego Bay. Seven of the eight bridges are maintained and operated by the State Divisioo of Bay Toll Crossings. In addition to the San Mateo - Hayward Bridge, they are the San Francisco - Oakland Bay Bridge, the Carquinez, Benicia - Martinez, Richmond - San Rafael, Dumbarton and Vincent Thomas Bridges. The latter spans the entrance to Los Angeles Harbor; the remainder are in the San Francisco Bay Area. The eighth toll bridge, the world - famous Golden Gate is operated by a special district, the Golden Gate Bridge and Highway District. We regard bridges as something special. They are vital transportation links, but they are even more than that. They are frequently symbols oi a community and are closely identified with the areas they serve. We look at bridges as structures which stand as monuments of beauty and utility for the present and the generations to come. The task of maintaining our bridges is one that is not taken lightly. On the Bay Bridge alone, almost 80 painters work continuously to keep the structural steel in perfect condition so that the crossing can continue its job of service in the years ahead. Hand in hand with the responsibility of maintaining the existing bridges - is the task of planning, designing and building new ones to meet the needs of a growing California. This also is the responsibility of the Division of Bay Toll Crossings. Traffic has been increasing steadily qri jail of our bridges; and at the same time the bridges have done their part to promote the economic development o9 the areas they serve. Some of our bridges are at the point of saturation and new crossings are needed to provide for the transportation requirement of the Bay Area. For years, the San Mateo - Hayward Bridge was a bottleneck, because the long, two - lane crossing with its traffic - delaving liftspan was becoming increasingly overcrowded. Now. we are completing a new, high - level bridge which already haswori widespread acclaim for its beautiful design. We are confident that, residents of the Bay Area will point to it with pride in the years to come. At the same time, its four - lane trestle and six - lane high - level section will provide a safe and easy passage over the bay for the increasing traffic of the future. We are also - engaged - in designing a new Southern Crossing, linking the southern part of San Francisco with Alameda and Bay Farm Island. This will provide a new and urgently needed crossing which will relieve the iricreasingly congested Bay Bridge and connect to new freeway approaches ftrand from San Francisco and the East Bay. It is a structure which will have a profound effect on the economic development of the Bay Afeain the . future. - 1 ' " .

The power system components and nJher electrical and mechanical devices are con trolled and contmaully moni tored by a solid - state multiplex system known in the trade a; an electronic monster.

Large compressors pro vide air to outlets at each pier The air will be used by bridge painters in their never - ending job of painting and maintaining the bridge steel. The compressors are automatically controlled to provide only the nec essary supply of air. They shut themselces off automaticaiiy when not in use. The steel towers which sun - port the main span flank the navigation channel under the bridge. Special lights and signals will direct ships as they approach and pass under the bridge. A wood Fender system around the bridge piers will prevent i damage from passible ship colli sions. The fenders will be pro tected from fire damage by a water spray system. Visual and audible alarms will be activated at the toll plaza by heat sensing and water. flow detection devices on the bridge. Bay Bridge Chief Lives In San Mateo E. R.
