Summary of work

Starting Feb. 1, 2021 rehabilitation of four historic bridges on Hwy 74 will start. The project is in Whitewater State Park near the south entrance. The road will be closed at the work zone during the project, which is expected to be completed in late October. 

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