The city of San Marcos plans to close two I-35 ramps near the San Marcos Outlet Malls, 3939 I-35, San Marcos, this week. The southbound I-35 exit ramp at Centerpoint Road and the northbound I-35 exit ramp at McCarty Lane will be closed from Thursday, Nov. 24 at 5 p.m. until Friday, Nov. 25 at 10 p.m. Motorists who had been planning to exit Centerpoint from southbound I-35 should take the McCarty Lane exit, and those traveling on northbound I-35 planning to take the McCarty exit should take the Centerpoint exit. "We plan with the city of San Marcos for months in advance to prepare for Black Friday because it’s one of the busiest weekends of the year," said Celena McGuill, marketing director for the outlet malls. McGuill said the outlets will open at 6 p.m. Thursday. She said she anticipates lines beginning to form outside stores early Thursday afternoon. Lines will likely remain at stores overnight Thursday and into Friday morning, she said. McGuill also encouraged shoppers to check the San Marcos Outlet Malls website to see which stores will be offering "deal busters." The San Marcos Police Department will also have units patrolling the outlet malls Thursday through Sunday, and a command post will be established at the outlets to organize police and fire department activities.
