BridgesThe North Carolina Dept. of Transportation is proceeding with a complex replacement of the Herbert C. Bonner Bridge on the Outer Banks, despite a new lawsuit that claims the project violates the National Environmental Policy Act.PCL Civil Constructors Inc. and HDR Engineering Inc. of the Carolinas submitted the apparent winning bid of $215,777,000 for the design-build project that NCDOT estimated would cost approximately $241.6 million.Replacing the deteriorating 2.7-mile, 260-span prestressed-concrete girder structure across Oregon Inlet has long been a top priority. It is the only highway link to Hatteras Island, one of the state's most popular tourist destinations and home
Workers on the Humpback Bridge replacement, located on the George Washington Memorial Parkway just north of Interstate 395 and immediately south of the Columbia Island Marina, are closing in on the final round of safety improvements.

The widening of I-405 marks one of the few major design-build projects in Los Angeles to date. But thanks to an ambitious initiative to build 12 major transit projects by 2019, rather than over three decades, alternative project delivery methods are expected to be deployed on some of the county's biggest rail and highway projects.One of the highway projects that might benefit is the decades-old Interstate I-710 completion. “This project has the most promising P3 potential,” said Doug Failing, executive director of highway programs for the Los Angeles Metropolitan Transportation Authority, or L.A. Metro. His remarks came during a May
As outlines of new House and Senate transportation bills come into sharper focus, it is clear the construction industry will be hard-pressed to get even a small federal funding boost above current levels for highways and transit. That outcome would be another blow to construction firms bracing for the end of the federal stimulus program and enduring spending cuts by state and local transportation agencies.Two plans are on the table. House Transportation and Infrastructure Committee Chairman John Mica (R-Fla.) on July 7 formally unveiled a $230-billion, six-year transportation framework. In the Senate, Environment and Public Works Committee Chairman Barbara Boxer
If all goes according to the Metropolitan Transportation Authority’s plan, Los Angeles will avoid the dreaded “Carmageddon” this weekend when a major highway section is sealed off.
