OKLAHOMA CITY (AP) Oklahoma has spent more than $63 million on a restoration project of its Capitol building that's expected to be completed in five years.

The project includes the restoration of the Oklahoma Capitol's interior and exterior features, along with infrastructure, The Oklahoman reported. Work on the century-old building is funded by bond issues.

"Since the last time we met, we've actually crossed over the threshold from the first issue of the first bond package," Trait Thompson, project manager told the State Capitol Repair Expenditure Oversight Committee.

Thompson said the project is now "into the second issue of the second bond package of the original $120 million that was authorized in 2014." He said he's pleased with the project's financial situation.

Lynnsee Boyse with exterior contractor J.E. Dunn Construction said construction is on schedule and that the exterior is expected to be completed by March 2019.

Officials with main contractor Manhattan Construction said 65 percent of the schematic design has been completed. The building's west-side ground floor also will be reopened soon.

Manhattan said it will begin working on the building's food service area, tourism office, restrooms and storage for the state Senate in 2018.

The interior of the Capitol is expected to be completed by 2022.
