This summer marks three years of construction on the Capitol Restoration Project. Project funding was first authorized by a $120 million bond issue passed by the legislature and signed by the governor in 2014. A subsequent bond issue was passed in 2016 for $125 million. Prior to the start of restoration activities, the State Capitol had appeared on Preservation Oklahoma’s “Most Endangered Places” list twice and the building had numerous life safety issues due to failing infrastructure, both on the interior and exterior. With each passing month, the Capitol is beginning to reclaim its former glory as areas inside and outside the building undergo meticulous restoration work.

To date, these are the accomplishments on the Capitol Restoration Project:
