Some of Missouri's major interstates have become major drug trafficking routes, according to police.
On Tuesday, Waynesville police found a $10 million stockpile of drugs by accident when they noticed several vehicles at a closed-down truck stop. Investigators found almost 100 pounds of cocaine and 90 pounds of meth.
For at least 20 years, Missouri police have been on the front lines of a national drug war.
Waynesville sits right off of I-44. It's an interstate drug traffickers like, according to Missouri Highway Patrol, because it's the most "direct route" to get drugs from Mexico to the northeast - to cities like Chicago and New York.
Police say another major drug corridor is I-70, a route for moving drugs west to east. Drug pushers also use I-55, police said, which covers the southeast part of the state.
Just last week, cops found nearly two tons of marijuana on a tractor trailer on I-55. The drivers, who were both from Texas, were arrested.
So far this year, 14 people have been arrested for drug trafficking on I-55.
Large drug busts on Missouri's interstates aren't anything new and the problem doesn't appear to be slowing. Highway patrol news releases from 2003 indicate several thousand pounds of meth, cocaine and pot were found along I-44 in just a few months.
Most of the time, police said the drugs are only passing through Missouri, not sold here. Still, police said anytime they can get drugs off the streets it's a good thing.
