Yosemite National Park is currently developing an Environmental Assessment (EA) to study rehabilitation on approximately 40 miles of the Tioga Road, the highest trans-sierra highway that crosses the northern part of the park. The primary goal of this project is to improve visitor safety along the Tioga Road while still preserving the natural and cultural resources throughout the Tioga Road corridor. https://www.nps.gov/yose/learn/news/tiogasitevisit3.htm
