A seven-vehicle wreck left a woman injured and a major traffic backup Monday morning on Interstate 65.

The wreck occurred at about 9:30 a.m. between mile markers 96 and 97 in the northbound lanes of I-65.

Central Hardin Fire Department Chief Everett Roberts said the incident included seven vehicles in three separate crashes.

Charles “Casey” Miller, 38, of Paducah said the initial crash began when his white Dodge truck hydroplaned for about 100 yards.
