Traffic was stopped on Interstate 675 Tuesday afternoon after a crash involving a semitrailer and a car resulted in a natural gas leak.
The highway was shut down just south of the I-70 interchange where the cab of the semi was overturned and leaking natural gas.
The crash happened just past exit 24 on the northbound side of 675 shortly before 1:30 p.m.
Most southbound lanes were reopened within 30 minutes, and at least one lane of northbound traffic was reopened by 3 p.m.
Both drivers were taken to the hospital to be checked out, but they are expected to be OK.
