SPRINGFIELD — Renovations are underway on the north wing of the Illinois State Capitol.

Plans include the construction of an underground parking garage, elimination of the circle drive and the addition of a new entry that improves access and security.

“We are very fortunate that we have a statehouse to be proud of,” said Andrea Aggertt, director of the Office of the Architect of the Capitol. “There are other states that have statehouses that look like a high-rise that you would see in Chicago, so we want to take care of a historic building and, unfortunately, the older buildings are the ones that need the most work.”

The scheduled renovations carry a total price tag of $224 million already appropriated by the Rebuild Illinois Capital Plan. The Illinois Senate will convene in the Howlett Auditorium after the 2022 spring session and will continue meeting there until January 2025, when renovations are set to be completed.

The plans for the renovations include:

  • New stairs to allow for emergency exits directly outdoors.
  • New fire alarms, sprinklers and lighting.
  • Accessible bathrooms, entryways and door hardware.
  • Modernized mechanical, electrical, and heating and ventilation systems.

The purpose of the renovation is to address safety and security concerns, but also to return the historic architectural detail to the Capitol.

The restoration will also return some of the history to the building that was completed in 1876 at a cost of $4.5 million, removing recessed ceilings, non-historic millwork and mezzanines from the north wing.

Construction for the underground parking garage will begin in coming weeks.

The goal of the renovation is to improve security by removing vehicles from close proximity to the building, creating a visitor-screening area on the outside of the structure and installing electronic locks and lockdown capability and duress buttons. Plans also include an underground conference and meeting-room area.

Currently, there is only one disabled-access entrance to the Capitol. In 2011, the west wing of the Capitol underwent a two-year, $50 million renovation. That met with scrutiny when the $700,000 price was revealed for three mahogany doors clad in copper. The original doors had been replaced in the 1970s with ones made of glass and aluminum.
