A multi-million dollar project along Interstate 540 saves lives.
Cable barriers were installed along a portion of Interstate 540 from Fayetteville to Bentonville last summer.
And officials say the barriers have already been hit more than 70 times in the last six months.
Dick Trammel of the Arkansas State Highway Commission says,
"We've already spent about $50,000 for repairs on the barrier. It has been hit 70 times, I'm going to guess we've saved 5 or 6 lives and it's worth every penny of it."
The 28 miles of barriers rang in around $5.1 million.
