The latest:
Tioga Road is open to through traffic only 10 am–11 am and 3 pm–4 pm daily until further notice. Stopping and day-use recreation are allowed. No visitor services are available.
Motorists can start driving from five miles east of Crane Flat (eastbound) and from Tioga Pass (westbound) from 10 to 11 am and 3 to 4 pm. Motorists do not need complete the drive at closing times (but parking is not allowed).
Bicycles are allowed during daylight hours; cyclists must be off the road by dark. No camping is available along the road. Parking for cyclists is available in any turnouts downhill from (outside of) the closure areas.
Snow clearing operations this year have made the road passable through the park but the water delivery and wastewater infrastructure in the Tuolumne Meadows area is still not ready to be used. In order to protect this fragile alpine environment from the impacts which come from human waste associated with the large numbers of visitors that utilize this area of the park when it is opened to the public, but still allowing for the motoring public to transit this important road corridor, the superintendent is allowing this limited access.
