Answers to Frequently Asked Questions
Why does it take so long to open the roads?
These are some common causes for slow progress of Tioga Road plowing:
For Tioga Road, once plows reach Tioga Pass, just one lane is plowed. Additional work is still required before the road can open:
Crews plow to the full width of Tioga Road and roads leading to critical infrastructure. During this time, several avalanche zones typically remain active.
Crews then shovel out infrastructure and begin the process of turning on drinking water and sewer systems. Meanwhile, other crews remove trees in danger of falling on the road and in developed areas, clear culverts on side roads, and replace signs.
Crews then work on setting up or de-winterizing buildings. Plowing and culvert clearing continues, and crews clear ditches and fill potholes.Just prior to opening, staff set up operations at the entrance station, wilderness/visitor center, and move into housing.
Will I be able to ride a bicycle on the Tioga or Glacier Point Roads before they open to cars?
In some years, these roads may be open during limited periods to bicycles prior to opening to cars. Any updates regarding pre-opening access on these roads will appear on this webpage. Unless otherwise posted here, both roads are closed to cyclists if they are closed to vehicles.
