ST. LOUIS (AP) -- There are no significant delays for drivers so far after the shutdown of a 5-mile stretch of Interstate 64 in the St. Louis area for a massive reconstruction project.

Missouri Department of Transportation officials say the 535 million dollar project is the single largest contract in the agency's history. The project will last two years, with one 5-mile stretch of the interstate closing today for a year and a second during 2009.

Officials on the project have said they expect another test on Monday, with more work and school traffic expected after the holidays.
