The project includes reconstruction of the city council chambers and the mayor's office, plus making the first floor bathroom more accessible.
The over $2-million project will be mostly paid for using COVID relief money.
Construction is set to start in the next week. City officials say they're expecting it to be finished by mid-August.
In the meantime, city council meetings will take place next door in the Rock Island County Office Building. And the city clerk, mayor and city manager's offices have moved to the east side of the building and can be accessed through the 16th Street entrance.
The Rock Island City Hall was built in 1940. This is the first major renovation since it was built.
