It is essentially a gigantic ditch, packed with equipment, concrete, rebar and thousands of laborers from many countries. It is a hotbed of construction challenges and a momentous sequel to one of the world's engineering epics: the original 1914 construction of the Panama Canal.

Bridge design engineers are addressing the challenge of cable-induced vibrations as modern cable-stayed spans grow in size.Construction of the island span and, five kilometers
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.
The Kentucky Transportation Cabinet expects to issue in October the first construction contracts for a $165-million bridge to replace the Eggner's Ferry Bridge over Kentucky Lake in the southwestern part of the state. Emergency repairs to the original 80-year-old span, which carries U.S. 68/Ky. 80 over the Tennessee River, originated this spring after a barge carrying rocket components struck the crossing in January.
As fuel costs and environmental concerns rise in conjunction with shrinking road budgets, cold in-place recycling paving, or CIRP, methods continue to gain interest nationwide. Cold in-place recycling has been used on low-volume roads for some time, but the technique may gain acceptance on higher-volume roads as well.
The status of a highly publicized $3-billion bridge-and-road program, seen as an economic driver for the impoverished nation of Bangladesh, remains unclear after the World Bank canceled a $1.2-billion credit, citing the government's "inadequate response" to charges of corruption on the project.

Aided by a presidential extension of Build America Bonds—and, somewhat ironically, by the recession—the $2.5-billion widening of the New Jersey Turnpike in the middle of the Garden State has reached its halfway point, with an average $1 million worth of construction occurring every day.
Wind-induced cable vibrations caused steel diaphragm plates to fracture and fail on a 2,200-ft cable-stayed suspension bridge in Minneapolis, according to a preliminary report prepared by Northbrook, Ill.-based engineer Wiss, Janney, Elstner Associates, the firm the city hired to investigate the cause of the failure.
