All lanes of Hwy 378 (Sunset Boulevard) are blocked in the 2800 block, according to the West Columbia Police Department. The eastbound exit ramp on I-26 onto 378 had been closed at about 3:30 p.m. Tuesday.
The road closure is just west of Lexington Medical Center. Police said "If you need to get to the hospital, please come from the east side of Sunset Boulevard. There is a large gas leak in the area. Avoid the area if possible."
Traffic, at one point, was being routed through the LMC parking lot.
