Governor Schwarzenegger attended a groundbreaking ceremony yesterday for the repaving and repair of Interstate Highway 80 in Fairfield (between state Highway 12 and Air Base Parkway), which is the first California infrastructure project to be funded by federal stimulus money. The 50-year-old stretch of highway is used by over 200,000 vehicles per day, and the $13.5 million project is said to provide 200 construction jobs. Top Grade Construction of Livermore submitted the lowest bid, which was 40 percent lower than Caltrans' cost estimate. The governor's office said the savings will be used for other highway projects. The project is expected to be completed by the end of the year. California is expected to receive nearly $850 million in federal economic stimulus money this month for transportation projects.
