Congestion is a major problem in certain areas of US state Florida. Large number of commuters and tourists means that central Florida’s Interstate 4 (I-4) highway suffers particularly from congestion. Its proximity to Disneyland means that the traffic often comes to a complete standstill. A 2012 report from the Texas Transportation Institute ranked Orlando 13th in the US for traffic congestion, with more than 1.5 million daily trips on I-4. The report estimates that each frustrated commuter wastes about 45
Concrete barriers offer a highway safety solution - Mike Woof writes. Concrete safety barriers are being installed on many of Europe's major highways, particularly for use as centre lane dividers. The strength and durability of concrete barriers can help reduce the risk of cross over accidents, one of several topics raised at a conference in Brussels on concrete highway barriers organised by the European Concrete Paving Association, EUPAVE.
The conference was opened by Yves Deceoene of the IRF's Belgian ex
Explosives were used successfully in the US to demolish the Long Island Bridge. The structure formerly provided a connection to Squantum's Long Island, however it had fallen into disrepair and a decision was made to remove the structure. A section of the Long Island Bridge was demolished by a specialist contractor. This saw the implosion of a229m section of the structure connecting with the island.
Demolition is a highly specialised business, as the machinery required to carry out the work on high-rise demolition contracts can be very site specific. Today's high reach demolition rig is no longer simply a tracked excavator with a long boom, indeed some machines cannot be used as excavators at all. Likewise a machine that is dedicated to carrying a 2.5 or 3tonne shear or hammer will need to be built to take the stresses and strains of demolition life.
