Interstate 64

Interstate 64 is one of the newer interstates in the state of Missouri. Currently, it is slowly being extended. From once ending just over the Illinois/Missouri State Line, to ending near Dardenne Prairie. I-64 through the StL Metro is named the Daniel Boone Expressway.

The December, 19th, 2004 St. Louis Post-Dispatch, said the state highway and transportation department has approved the location for a new bridge over the Missouri River. A new four-lane bridge will built west of the current eastbound bridge, which opened in 1989. It will be many year though until the bridge is built. When completed, the new bridge will carry eastbound traffic. The current eastbound traffic will carry traffic west into St. Charles County. The original bridge at the site, which currently carries westbound traffic, was built in 1937. It will become a ramp from Chesterfield Airport Road to WB I-64/U.S. Rt. 40; NB U.S. Rt. 61. As of now, no money is avalible for the project. The state projects that it to be built near 2012 to 2020.

In May, 2009, the Missouri legislature passed House Bill 1198. This names the streach of Interstate 64 from the St. Louis City Limits to the Illinois State Line, as "Jack Buck Memorial Highway". Jack Buck was the voice of the St. Louis Cardinals for over 50 years. Interstate 64 runs just south of the Cardinals ball park, Busch Stadium, in Downtown St. Louis.
