Monday, November 7th, 2011FEDERAL HIGHWAY ADMINISTRATION
The main goal of this project was to use Long-Term Pavement Performance (LTPP) Specific Pavement Study (SPS) experiment data to assess the impact of different design, construction, and rehabilitation features on pavement response and performance for specific site conditions. The analysis sought to identify which features could help achieve the best short-term and long-term performance and to evaluate the effectiveness of common maintenance practices used for flexible and rigid pavements.
Bridging the Gap: Redirecting Investments to Fix the Nation’s Bridges
Friday, November 4th, 2011TAXPAYERS FOR COMMON SENSE
A large portion of the nation’s 600,000 bridges are in poor condition and require investment to repair or replace. Congress, by virtue of its control of spending and oversight, can encourage states to spend a greater share of transportation funding on maintaining and fixing existing infrastructure. If we are to reduce the number of deficient bridges in our transportation system – currently 11.5 percent of all bridges are deficient – Congress must be part of the solution.
The Fix We’re In For: The State of Our Nation’s Bridges – Metropolitan Bridge Rankings
Wednesday, October 19th, 2011TRANSPORTATION FOR AMERICA
Structurally deficient bridges in metropolitan areas carry a disproportionate share of all trips taken on a deficient bridge each day. In fact, deficient bridges in the largest 102 metropolitan areas carry three-quarters of all traffic crossing a deficient bridge. Put another way, there are more deficient bridges in these 102 regions than there are McDonald’s restaurants in the entire country – 18,239 versus about million 14,000. Worldwide, McDonald’s serves a staggering 64 million people a day. But here in America, 210 million trips are taken daily across deficient bridges in just these 102 regions.
Federal Highway Administration Budget Estimates: Fiscal Year 2012
Thursday, August 18th, 2011FEDERAL HIGHWAY ADMINISTRATION
FHWA’s FY 2012 budget requests $70.5 billion ($69.9 billion net of rescission) and represents a new paradigm in funding our nation’s highways. This request represents the first year of the Administration’s six-year surface transportation reauthorization proposal, which provides $336 billion from FY 2012 to 2017 for highway programs. The proposal reflects a 48 percent increase in funding for road and bridge improvements and construction from the $227 billion authorized in the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU).

Monday, November 29th, 2010From Fast Lane, the Official Blog of the U.S. Department of Transportation: The currently standing Gerald Desmond Bridge links Los Angeles and the Port of Long Beach, a bridge so active that Port of Long Beach Executive Director Richard Steinke called it “…the workhorse of the goods movement system.” Unfortunately, at 42 years old, the [...]

Wednesday, September 22nd, 2010THE ROAD INFORMATION PROGRAM (TRIP)
Nearly a quarter of the nation’s major urban roads are rated in substandard or poor condition, providing motorists with a rough ride and increasing the cost of operating a vehicle. While the share of the nation’s major urban roads in poor condition decreased from 2007 to 2008, potential deficits in state budgets, the completion of federal transportation stimulus projects and the failure of Congress to approve a long-term federal surface transportation program, may lead to worsening urban pavement conditions.
