Yosemite National Park Road Crews will begin spring snow removal operations on Glacier Point Road on 04/01/2014 and Tioga Road on 04/15/2014. To ensure a safe work zone during working hours no traffic, including administrative (vehicle, bicycle or foot) will be allowed. Work schedule is Monday-Thursday 6:30 AM to 5:00 PM. For non-work hour access contact the appropriate District Ranger. This schedule only addresses snow removal. Additional road, hazard tree, building and utility work will be required before opening the high country areas to administrative and public access.
