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.

Wildlife-vehicle collisions are an ever-present threat in rural areas around the world, and there is certainly nothing funny about suddenly finding an angry moose in your headlights on a sharp bend. A variety of detection and avoidance systems are currently in use or under development to help prevent your vehicle being

    IRD, Inc's Terry Bergan discusses future applications of weigh in motion technology. The application in recent years of Weigh In Motion (WIM) at tollgates has been driven by recognition of the fact that there is economic value, which can be levied, attached to Heavy Goods Vehicles (HGVs) which haul laden (and are therefore heavy) rather than empty. As wear and damage to road surfaces increases exponentially with weight, the targeting of HGVs in particular makes sense from both the economic and maintenance p
