A major interchange is undergoing a role reversal in Arizona's second- largest metropolitan area. Designed to solve traffic headaches and a dire safety problem, the Interstate 10 interchange project in Tucson is "flipping" the grade of Prince Road so that it will pass over, instead of under, I-10.
State transportation departments wishing to replace bridges faster using accelerated bridge construction, or ABC, techniques will soon have a standardized design tool kit as a reference.

As the cable car will be serving some venues for the London 2012 Olympic Games, engineers are in a hurry to complete the $71-million project before the opening ceremony in July.Being
By all accounts, Dr. David Carrier III is an eminent geotechnical expert on soil science. A paper he co-wrote won a medal from the American Society of Civil Engineers, and he has written about building conditions on the moon.
The U.S. Green Building Council announced recently that its Leadership in Energy and Environmental Design program now will recognize credits from the Building Research Establishment Environmental Assessment Method, or BREEAM.
With no time to wait for esoteric designs for the largest-ever nuclear fusion reactor to take final shape, engineers are pushing ahead with $1.3 billion worth of building and infrastructure construction at a plant site in Cadarache, France.
A landmark agreement between the New York State Dept. of Environmental Conservation and the New York City Dept. of Environmental Protection has green-lighted $3.8 billion in funding over the next 18 years to address combined-sewer overflows, or CSOs.
Surprisingly positive results from the first of four large-scale tests of reinforced-concrete link beams with embedded structural steel sections have further opened the door to more-constructible concrete towers in highly seismic zones. Link beams over openings in concrete shear-wall cores have long been the bane of builders because of intense reinforcing-steel congestion, which slows construction.During the first-ever large-scale test, the beam performed much better than anticipated. Given the importance of link beams in core-wall buildings, understanding performance at a meaningful scale is of "critical importance," says Ron Klemencic, president of structural engineer Magnusson Klemencic Associates (MKA), Seattle.MKA is one of
India plans to boost infrastructure spending to $1.2 trillion as part of the country's 12th Five-Year Plan for the years 2012-2017, with the amount set to come from private investment rising to 50% from, during the last plan, 30%. Finance Minister Pranab Mukherjee noted the figures on March 16, when he announced the country's 2012-2013 budget.
