A banner with the words "Find Erica Hernandez" was unfurled on the Montrose bridges over the Southwest Freeway on Monday afternoon to help raise awareness about the case.
Congresswoman Sheila Jackson Lee, whom the family reached out to for help in increasing resources for the search, joined them after the banner drop.
"We can't imagine there's not someone out there with information, so the family is begging for people with any kind of information," Jackson Lee said. "We don't know what might've happened, but we know that she's a loving mother, and she has three beautiful children that want her to come home."
Electronic billboards also went up across the state.

The FBI is now investigating Hernandez's disappearance, but there are no signs of her.
Her family, along with community volunteers, split up into groups and passed out flyers Sunday throughout Houston after search efforts were impacted by weather conditions for the second weekend in a row.
Family members said Hernandez is a single mother who works full-time to care for her three children. She even donates plasma twice a week, trying to bring in more money for her household.
Her son, Dennis, turned 16 years old last Wednesday. Hernandez's sister, Ashley Hernandez, said there's no way in this world his mom would miss his birthday.

"We still need to find her. That's the whole point, you know. Whether I think the outcome is going to be good or bad, we still need to find her and we still need her. We need her for her family, so I'm not exactly sure where their mind is at, but my mind is not in a good place," Ashley told ABC13.

Family said Hernandez left her friend's home around 2:30 a.m. Sunday. She reportedly sent a text around 3:04 a.m. stating she was "five minutes away from getting home."
Ashley told ABC13 that detectives believe Hernandez was spotted near S. Post Oak and Court Road. That's where the family has turned the focus of their search and other routes that she may have taken to get home.
