Siler City, NC -- Emergency officials say they do not expect to open U.S. Highway 64 in Chatham County until later Friday evening.
Crews continue to clean up an ammonia leak that has kept all of the lanes closed since yesterday afternoon. They are hoping to complete the work by 8 p.m this evening.
The highway has been closed between Arthur Teague and Silk Hope roads since an accident involving a gas truck and tractor-trailer Thursday afternoon caused the leak.
Six homes were evacuated Thursday night as a safety precaution. Those people have since been allowed to return home.
Hazmat teams spent the day unloading the remaining ammonia from the tanker.
State troopers say the accident occured when a tractor-trailer heading west on U.S. 64 got a flat tire. The driver pulled off to the side the road but did not completely get the trailer out of the lanes of traffic.
A gas truck heading the same direction hit the tractor-trailer, putting a hole in the truck's gas cap. County officials confirmed the gas truck then began to leak ammonia.
The driver of the gas truck suffered minor injuries, troopers said. The tractor-trailer driver had got out of his vehicle before the accident and was uninjured.
Troopers said they must inspect the vehicles and finish their investigation before they make a decision on filing any charges.
County officials recommended that those needing to travel between Pittsboro and Siler City take the following detour:
From Pittsboro: Go about 11 miles on U.S. Highway 64 West. Take a right on Arthur Teague Road for nearly 4 miles until you come near the Silk Hope community. Take a left onto Silk Hope Road, which goes back to U.S. Highway 64. Take a right toward Siler City.
From Siler City: Go about 4 miles east toward Pittsboro. Take a left on Silk Hope Road. In approximately 4 miles, take a right on Arthur Teague Road to get back to U.S. Highway 64.
