| Importing pavement innovation |
| October 21, 2009 CE News |
The use of geotextiles in pavements is hardly a new thing. They can be commonly found between and within subgrade and base layers to mitigate the effects of poor quality materials, as a filter around subdrains, and along embankments for stabilization. However, the use of geotextiles as an interlayer between cementitious layers in concrete pavements is not common in the United States — at least until now. |

| First and 10: ODOT tackles $147 million Willamette River Bridge |
| October 16, 2009 Oregon Department of Transportation |
| The golden shovels flashed in the Oregon summer sun on Aug. 11, 2009. Transportation advocates U.S. Sen. Ron Wyden and U.S. Rep. Peter DeFazio helped Oregon Department of Transportation Director Matt Garrett and those of us on the project team break ground to begin construction on the Interstate 5 Willamette River Bridge at Eugene and Springfield.
With the groundbreaking, the goal line is finally in sight, though we still have many yards to go: The bridge’s anticipated completion date at the end of 2012 is now closer than the beginning of our journey to the kickoff ceremony... |

| Chisholm Trail gets five-level interchange |
| October 3, 2009 CE News |
During the late 19th Century, Texas cattlemen started pushing their longhorns along the Chisholm Trail to reach the Kansas rail heads. Little did these trailblazers realize that their efforts to drive cattle northward to market would ultimately influence transportation infrastructure in the state. Now, more than a century later, HDR and its collaborative team are helping the North Texas Tollway Authority, Texas Department of Transportation, and the city of Fort Worth to design an interchange to drive people along the routes of this founding cattle trail.

| Advances in wastewater collection and treatment |
| October 3, 2009 CE News |
| Wastewater collection and treatment arguably ranks among the most significant advances in public health in the United States. Yet today, the public is largely unaware of the civil infrastructure that has virtually eliminated diseases that spawned deadly epidemics in this country during the last century. Nevertheless, many aging municipal wastewater systems now need rehabilitation, replacement, or expansion, and new technologies and design tools are poised to take the wastewater industry to new heights in sustainability, energy efficiency, and cost effectiveness. |

| Redecking Michigan’s Cut River Bridge |
| September 15, 2009 Rebuilding America's Infrastructure |
| Like its famous younger cousin just to the east, the mighty Mackinac Bridge, the U.S.-2 bridge over the Cut River is known for its elegant construction and breathtaking views of Lake Michigan.
The 62-year-old structure became such a tourist attraction that in 1985 it was widened to accommodate sidewalks on each side for pedestrians who had previously braved passing logging trucks to snap photos from the railings. It was this widening project that added complexity to the Michigan Department of Transportation’s (MDOT) planned redecking of the historic bridge in 2008. |
