Bicycles on Tioga Road - On Friday May 15, Tioga road will be open to all vehicles to Yosemite Creek and to bicycles
to May Lake junction. Administrative travel is allowed beyond Yosemite Creek gate. Please keep in mind that signage
along the road is accurate because it is updated each day as conditions change. A sign at May Lake junction indicates
that bicycles are not allowed past that point. Also, any administrative traffic should be on the lookout for bikes so that we can
provide visitors that experience without interfering with opening operations. (S. Sprouse - 5/13/09)
