High-Speed Passenger Rail: Preliminary Assessment of California's Cost Estimates and Other Challenges
GAO-13-163T: Published: Dec 6, 2012. Publicly Released: Dec 6, 2012.
Based on an initial evaluation of the California High Speed Rail Authority's (Authority) cost estimates, GAO found that they exhibit certain strengths and weaknesses when compared to best practices in GAO's Cost Guide. Adherence with the Cost Guide reduces the risk of cost overruns and missed deadlines. GAO's preliminary evaluation indicates that the cost estimates are comprehensive in that they i...
Information on Materials and Practices for Improving Highway Pavement Performance
GAO-13-32R: Published: Nov 14, 2012. Publicly Released: Nov 14, 2012.
The nation's more than 4 million miles of roads are key to the economy, facilitating the movement of goods and people. Although highways are highly durable and can last for decades, they deteriorate from traffic wear and tear, inadequate drainage, construction deficiencies, and weather. Keeping them in good condition requires substantial resources: public entities spent more than $180 billion in 2...
