Live 5 Investigates: Dangerous intersections

"I'm surprised it's just that little," Thomas Grant, driver, said. "Because you go from two lanes to four lanes, and when you take that turn on the left two lanes, that turn is so sharp, the slightest mistake you're going to hit that person to your left."

According to the latest census data, Berkeley, Charleston and Dorchester counties are among the fastest growing in S.C. Deputy Chief Coyle Kinard with North Charleston Police's department of Special Operations said he's indeed seen an uptick in traffic moving through Ashley Phosphate. 

"The increase in volume of vehicles is unbelievable up in that area," Kinard said. "A lot of people coming through the city heading to Goose Creek, also heading to the Northwoods area that live up there and work in the Tricounty area."

"What we've been finding recently," Kinard said, "Even though you've got two turn lanes turning onto Ashley Phosphate to head towards Dorchester, people are also using the third lane as a left turn lane." Kinard said it's one issue on the department's radar for increased enforcement. 

In fact, Kinard said officers are frequently positioned near such intersections during rush hour to help clear accidents more quickly or monitor traffic. 

"It's just kinda scary," Jacqueline Gaytan, who lives in North Charleston, said. "It doesn't even matter what time it is, it's just always always busy."

Meanwhile, more than 170 accidents were investigated at I-26 at College Park Road, according to officials. Public safety officials accounted for 117 incidents at the Carnes Crossroads intersection of 17-A and Hwy 176. The latter is no surprise to Major John Grainger with Goose Creek Police. 

"You could have a million cars on this interstate without a collision," Beres said. "It's the drivers' behavior that causes them."
