SAN ANTONIO -- A walk in Brackenridge Park took a frightening turn for a 20-year-old San Antonio woman, who said she slipped into the San Antonio river at a popular spot at the park and nearly drowned.

She said she wants her accident to be a lesson for everyone, including the city of San Antonio.

"I felt like (there was) no way I could get out," said Alyssa Suarez, describing how she felt after slipping into the river.

Suarez said she feared for her life after falling into the river while walking on the vehicular bridge, a popular spot for motorists to drive their vehicle over the river at Brackenridge Park.

"My head went under, I was struggling to get up and my boyfriend got me up," said Suarez.

Suarez and Brandon Johnson were taking a walk through Brackenridge Park and decided to walk on the concrete bridge.

"I pulled her right out here beyond the sticks," said Johnson, pointing to the area where he said his girlfriend fell in.

Both he and Suarez said they thought she was stepping on the street, but instead it was sticks and debris.

After gulping a mouthful of river water, Suarez said she was caught up in an undertow.

"I felt how strong the current was and I didn't think Brandon would pull me out and I thought I was going to die," said Suarez.

She said the river tasted like sewage water.

Originally Suarez said she there were no warning signs posted at the vehicular bridge but later admitted she spotted two signs on each end of the bridge when she returned to the bridge a few days later.

Suarez said in the past she has seen children on the bridge and insisted the two signs are not enough. She also stressed the need for the city to make sure the bridge is clean from thick debris.

A city spokesperson said the incident is an isolated case and encouraged people to follow their warning signs posted.

A San Antonio Parks and Recreation spokesperson also said they will review the site and, if necessary, will add more signage. The spokesperson said a city crew will also be sent to the bridge to clean up the debris.

Suarez said she just wants to make sure the park is safe since Easter is just around the corner and children flock to the area. She said a near drowning will hopefully create a wave of caution on both sides.
