Summer Construction Means Slower 25 Treasure Island Service  

Starting Saturday, June 17, 2023, trips on the 25 Treasure Island route will take longer due to construction. This change will also impact frequencies during the daytime. On weekdays, buses will run every 20 minutes, and on weekends, buses will run every 30 minutes. Late-night service will not change.  

The 25 Treasure Island will continue to service all current stops, but it will follow a new routing to and from the Bay Bridge. This is due to closure of the existing on- and off-ramps that the bus uses, which will add time to each trip. The number of buses currently assigned to the 25 Treasure Island will remain unchanged, but the longer travel times will affect its frequency.

These changes are in addition to the previous changes that went into effect on February 13, 2023, as described below.
