Ice is present on roadways and bridges throughout San Marcos, and drivers are being urged to take it slow or stay off the roads entirely, according to a news release issued by the city.

Bridges at Wonder World Drive, just west of I-35, are closed due to slick conditions and will reopen once additional deicer is applied, the release said. Some non-elevated sections of I-35 may also be covered with ice.

During the early hours of Feb. 13, San Marcos Police Department officers responded to more than a dozen ice-related crashes on both sides of I-35. The city said no one was seriously injured.

From 4:30 a.m. to 6:30 a.m., I-35 was closed and treated for ice, with traffic diverted to access roads. However, the city said roadways and bridges are still slick and dangerous, and winter weather conditions are expected to continue throughout the weekend.
