Each and every work day more than 180,000 motorists endure the convergence of highways north of Dallas/Fort Worth International Airport. Just a few years ago, the limited number of lanes and criss-crossing interchanges resulted in constant traffic congestion, which earned the stretch an unflattering nickname – The Funnel.

Mounted on self-propelled motorized wheel transporters, each of the 3,100-ton gates was off-loaded onto a temporary dock on the Atlantic side of the waterway, not far from the new locks that will be their permanent home.The gates, costing about $548 million to fabricate and install, are the centerpiece of the enormous third set of locks that is being

For each primary process—batching, conveying and placing—the material is tightly controlled.The sheer volume of concrete—more than five million cubic meters—has to be built to meet the structures' projected century-long life span. As a result, the quality standards for the concrete are extremely high. The entire lock worksites on the
The quality standards set for the locks for the Panama Canal's Third Lane Expansion are enormously high, partly due to seismic risk. While the danger posed by earthquakes is perceived to be low, studies by the Panama Canal Authority (ACP) found evidence of an active fault running next to the new locks on the Pacific side of the canal.
In response to the dramatic growth of Panama City in recent years—along with severe traffic congestion—a design-build team is constructing a 14-kilometer, $1.8-billion light-rail line that will be the first of its kind in Central America.
