Motorists in south San Marcos will have to take an alternate route if they were planning to take the McCarty Lane exit ramp on northbound I-35 this weekend.

The exit ramp will be closed beginning at 7 a.m. Saturday through 8 p.m. and again at 9 a.m. Sunday through 6 p.m. to aid traffic flow during tax-free shopping weekend.

The outlet malls, which are located one exit south of McCarty Lane on Centerpoint Road, can cause heavy traffic during tax-free weekend. Lighted signs on the interstate will notify motorists of the closed exit ramp.

For more information, contact the city’s transportation division at 512-393-8036.
