San Francisco Bay Bridge east span opens

After years of delays and cost overruns, the newly built US$6.4 billion eastern span of the San Francisco-Oakland Bay Bridge opened with few problems other than the traffic snarls that were common around the toll plaza of the old span. The single pylon suspension span replaces a structure that was damaged during the 1989 Loma Prieta earthquake. It is designed to withstand the strongest earthquake estimated by seismologists to occur at the site over a 1,500-year period.

After years of delays and cost overruns, the newly built US$6.4 billion eastern span of the San Francisco-Oakland Bay Bridge opened with few problems other than the traffic snarls that were common around the toll plaza of the old span.

The single pylon suspension span replaces a structure that was damaged during the 1989 Loma Prieta earthquake. It is designed to withstand the strongest earthquake estimated by seismologists to occur at the site over a 1,500-year period.

One of the busiest spans in the United States, the single-towered, 634 metre long self-anchored main span is more than twice the length of the previous record holders, Japan's Konohana Bridge and South Korea's Yeongjong Grand Bridge, according to the Structurae engineering database.

It has been completed six years behind schedule at five times over budget. It will be used by some 280,000 daily commuters.

    Toshiba International is to replace over 20,000 high-pressure sodium (HPS) street lamps in San Antonio, Texas with LED luminaires. The city’s existing 250-watt HPS luminaires consume 310 system watts and are being replaced by Toshiba’s 100-watt 42-chip TGT LED luminaires. According to Toshiba, product durability and low energy consumption means LED lighting provides one of the lowest life cycle costs of any lighting technology.

    A new traffic management solution is attempting to bridge the gap in information available on freeways and arterial roadways. Andrew Bardin Williams reports. Agencies responsible for national networks of roads around the world have the ability to measure, analyse and disseminate accurate travel information to drivers. Millions of dollars go into data collection infrastructure to collect traffic congestion and travel time information on major freeways or highways. For example, a driver on the I-210 in the Lo
