The 39th Annual Taste of Chicago kicked off Wednesday in Grant Park. Officials with Chicago Fire Department said there at least eight people were transported or treated for heat-related illness.
It's unclear the conditions of each of the five people but the message is clear - if you don't take the proper precautions, including staying hydrated or limiting your exposure to sun, things can take a dangerous turn.
The temperatures were so hot, pavement in two northbound lanes of Lake Shore Drive buckled, causing traffic delays.
On the 92nd Street Bridge, firefighters had to hose down the swing bridge to keep it from expanding.
The South Shore Line was put on a high temperature speed restriction, delaying commuters on the ride home.
"It feels as if it's a million degrees," said Lorelai Rivera, commuter.
At the Taste of Chicago, emergency officials were stationed throughout Grant Park, assisting with the many who succumbed to heat-related illnesses. Many sought shade trying to escape the heat.
"I'm very glad I brought this umbrella," said attendee Lesley West. "Otherwise I'd probably be having to get transported as well because it's really hot out here."
This year, 80 restaurants will participate in the festival, including 24 pop-ups and 17 food trucks. The city said 36 of the participating food vendors are new.
