Parsons Brinckerhoff
|
| The Chicago Transit Authority (CTA) awarded a construction management contract to Parsons Brinckerhoff (PB) for a rail replacement and tunnel rehabilitation project on the system's Blue Line subway, which connects the downtown business district with O'Hare International Airport. The $88 million project is one of the first in Chicago to be fully funded by the American Recovery and Reinvestment Act of 2009. It involves replacement of 31,000 existing wooden half ties with new concrete half ties and 6,200 track feet of stone ballast with new concrete slab and direct fixation fasteners. |

| The summer of stimulus: doldrums, dawdling and boondoggles |
|
August 25, 2009
The Los Angeles Times

| Over the last week, I've noticed a trend in the coverage of the transportation industry: From editorials in Florida, to features in Los Angeles, a certain family of words and terms is being used with regularity; a family of descriptors, such as "dawdling," "boondoggle," "run-of-the-mill," and my personal favorite, "nincompoop." Even without reading these stories, the subtext of complacency is clear. This is not uncommon this time of year, as many Americans are out of the office and on vacation (or in the office, and yet, on vacation.) The Beltway crew is due back from recess soon, and the “public option” will dominate conversation upon their return. How much attention will transportation get? According to ProPublica.com, the U.S. Department of Transportation has spent thus far only $1.5 billion of its stimulus allotment, and as we’ve all seen, many of those projects have been perfunctory and low-impact. SAFETEA-LU expires in just over a month, and the 18-month delay is virtually a done deal; some have said it could be as long as four years before a new piece of transportation legislation is passed. It seems that when it comes to transportation, doldrums and static logic aren’t isolated to August. What will it take for our bridges and roads to get real attention? |
