Commuters headed toward SFO, Daly City or the East Bay from the Balboa Park station on Sunday will face 'major delays,' according to a recent alert from BART officials.

Passengers attempting to travel down any of these routes will be redirected to MUNI's 14R bus from Daly City toward Mission St. and downtown San Francisco. Additionally, mutual aid will be provided for riders via MUNI Metro Service from the city toward Balboa Park.

BART is now recovering from the incident, but 20 minute delays will persist at San Francisco stations in the direction of Antioch and SFO.

The stoppage was caused by an unknown 'major medical emergency' unrelated to planned track safety upgrades occurring between Orinda and Walnut Creek. Those delays could last up to 30 minutes.

BART asks that its riders 'plan accordingly' prior to their travels by using its Trip Planner tool online or via the BART app. They can also stay up to date on the transit organization's Alerts and Advisories page.

BART has not yet responded to SFGate's request for comment. This story will be updated with more information as it becomes available.
