OKLAHOMA CITY (AP) — The Oklahoma Transportation Commission has approved a work plan that calls for repairing or replacing nearly 400 county bridges and improving hundreds of miles of county roads over the next five years.

About $926 million in federal, state, local and tribal funds will go toward the County Improvement for Roads and Bridges plan that was approved on Monday, The Oklahoman reported. The plan is administered by the state Department of Transportation.

Transportation officials said that the bridges to be rehabbed or replaced include nearly 300 bridges deemed structurally deficient or functionally obsolete. They say more than 40 of the planned bridges will use bridge beams repurposed from an old interstate expressway. More than 2,000 beams from the Interstate 40 Crosstown Expressway have been available to Oklahoma's counties to use for local projects since it was taken down in 2012-13.

The plan also calls for improving more than 800 miles (1,287 kilometers) of county roads.

Shannon Sheffert of the state Transportation Department said the current work being done at the MacArthur Boulevard bridge over Deer Creek in northern Oklahoma County is a good example of the project, which is serving an important purpose.

"That's about a $5 million bridge project," he said. "That gets everything up out of the flood plain in that area."
