WILX.com is reporting that Michigan's State Capitol will undergo a major renovation project, expected to take two years to complete. It will cost taxpayers nearly $70 million.

According to the report, the project will upgrade heating and cooling systems, electrical systems, and other infrastructure issues that haven't been replaced in nearly 30 years. The upgrades will make the building much more energy efficient, according to spokespeople.

During the two year project, the building is expected to stay open, with the exception of the west side.
