SHORT-WAVE PHONE SYSTEM SERVES BRIDGE BUILDERS

Curiously, radio is helping to build a bridge.

Special short-wave transmitting and receiving sets make possible communication among groups of contractors scattered on land and water along the eight-and-one-quarter-mile route of work on the San Francisco-Oakland bridge. These men on the job also talk with the head offices and with the office of the state engineer in San Francisco.
