Detour was removed and project was completed Oct. 1, 2021. The project started Feb. 1, 2021 and included rehabilitation of four historic bridges on Hwy 74 in Whitewater State Park near the south entrance. The road was closed at the work zone during the project.

The work on the four bridges included repair of floors and walls. Starting the project in the winter made the work under the bridge easier as less water was flowing than when the snow began to melt in the spring. There was also soil work and rock placement around the bridges to prevent erosion. The numbers of the bridges are 8592, 8593, 8594 and 8595.
