Two huge events are expected to cause some major traffic congestion throughout San Francisco over the next week.

The Hardly Strictly Bluegrass Festival started on Friday in Golden Gate Park. The music event is expected to attract upwards of 60,000 people for each of its three days. The San Francisco Examiner reports that the San Francisco Municipal Transportation Authority has already shut down many roads in the park nearest the festival (taking place at Speedway, Marx and Lindley meadows). But Muni is also adding increased service to its N-Judah, 5-Fulton, 29-Sunset and 28-19th Avenue routes according to spokesman Paul Rose.

Also starting on Sunday is the annual Oracle OpenWorld convention at the Moscone Center. Muni has already shut down Howard Street between Third and Fourth streets through the afternoon of October 7. Mason Street between Ellis and O’Farrell will also be closed starting early Saturday morning. Detours have been set up around Moscone Center and bus lines in the area will also be rerouted.

Muni officials suggest taking public transit to cut down on some of the expected congestion in those areas.
