Illinois Gov. J.B. Pritzker said the state is moving forward into phase four on Friday, which will allow indoor dining, museums, zoos and other businesses to resume.
"The doctors and public health experts have reviewed the data and the proposed conditions for greater public activity and work conditions and have approved them, including the following activities with Covid-related health safety guidelines," he said.
"Hundreds of thousands more Illinoisans will be able to return to work," he added.
Pritzker said the state had seen a dramatic decline in Covid-19 deaths. It also significantly reduced its Covid-19 positivity rate, hospitalization and bed use in intensive care units, he said.
Illinois has a total of 139,434 Covid-19 cases and at least 6,810 people have died from the virus.
