After years of snafus, political battles, and funding fits and starts, New York City’s next major transit extensions are taking shape.Newly bored caverns deep below city streets and railyards provide hidden testimony to the construction team’s accomplishments, all while the nation’s busiest subway and commuter rail network strains to carry millions of passengers to and from the city. The next tunnels are a study of firsts, many side by side. Two giant tunnel-boring machines, crawling along like worms underneath the Big Apple, made transit history. Below neighborhoods on Manhattan’s West Side, they both achieved a difficult 90° turn, helped by
When Gilberto Neves, chief executive officer of Miami-based Odebrecht Construction, called Eloise Gonzalez in the middle of the night to come with him on an emergency trip to earthquake-torn Haiti, she was astounded.
Thousands of piles dot the Middle Eastern desert, spreading out in a T-shaped formation. They are the foundations of what will become a 700,000- square-meter airport terminal—and one of the foundations of Abu Dhabi’s ambitious 21st-Century infrastructure plan. The emirate’s long-term goal, to become a top destination for world trade and a cultural crossroads for the East and West—is getting an upgrade. The project now includes green-building and sustainability goals, as well as a growing number of western engineers and consultants brought in to help manage the $2.5-billion Abu Dhabi International Airport expansion and a slew of other projects. “There
Call it recycling on a whole new level at San Francisco International Airport: The $380-million Terminal 2 project features 99% recycling of construction materials. Airport tenants also need to meet a 10% waste recycling minimum. Rental-car drivers will get discounts for using hybrids. Even the landscaping is an exercise in sustainable approaches to harboring protected species. “We use goats,” says Sam Mehta, environmental services manager for SFO. “It is 100% sustainable. The grass is eaten and fertilized. For them, it’s an all-you-can-eat buffet, and they don’t harm the California red lake frog and San Francisco garter snake. The cut grass
Falsework is coming down this month after supporting the construction of what officials believe is the only transit bridge in the world to cross over an active taxiway.

The 740-ft-long cast-in-place box-girder bridge is the centerpiece of a two-mile-long transit system that will connect
Falsework is coming down this month after supporting the construction of what officials believe is the only transit bridge in the world to cross over an active taxiway. The 740-ft-long cast-in-place box-girder bridge is the centerpiece of a two-mile-long transit system that will connect two of Phoenix Sky Harbor International Airport’s terminals with off-airport transportation facilities.

The Phoenix office of Irving, Texas-based Austin Bridge & Road holds an approximately $6-million subcontract to
The tenuous fate of an estimated $8.7-billion trans-Hudson River rail tunnel exemplifies a dilemma faced by the American transportation industry as a whole: how to fund crucial megaprojects at a time when raising fuel taxes is political suicide and passing a multiyear transportation bill remains a pipe dream. + Image Photo: NYNJ Port Authority New Jersey Gov. Christopher Christie (R) announced on Oct. 7 that he was killing the project, called Access to the Region’s Core (ARC) and in development for almost 20 years. But after a quickly arranged meeting with U.S. Transportation Secretary Ray LaHood and Federal Transit Administrator

Airports in Southern California, one of the nation’s most heavily populated regions, are building as much and as “green” as they can with limited space and tight budgets. Modernization projects at the San Diego, Long Beach and Los Angeles airports are requiring engineers to think creatively.

Call it Underground Zero. In the middle of the World Trade Center site in Manhattan, workers are performing an intricate balancing act with steel and concrete, excavating beneath an active subway line while a number of other projects progress around them. The top-down permanent underpinning of the subway tunnel will create much-needed space for a new nearby iconic transit station as well as other facilities.
