What to know for bicyclists:


During weekdays there will be NO BICYCLE ACCESS between the Bay Bridge and Treasure Island along Macalla Road. (Visa Point will be OPEN for use from sunrise to sunset during weekdays for bicyclists.)

Weekends and Holidays

During weekends and holidays, bicycle access between the SFOBB bike path and Treasure Island will be provided via a temporary bike path between the SFOBB bike path landing at Yerba Buena Island and Macalla Road.

Bicycles will be able to travel between Yerba Buena and Treasure Islands via Macalla Road and the temporary bike path. Please note that Macalla Road is VERY STEEP AND NARROW, and there are no separated bicycle facilities along this road. Therefore, bicycles will need to share the lane with motorists. For these reasons, bicycles on Macalla Road are discouraged. The Vista Point facilities will be OPEN for use from sunrise to sunset on weekends and holidays for bicyclists.

What to know for pedestrians:

Weekdays, Weekends, and Holidays

Since there are no pedestrian facilities along Macalla Road, there will be no pedestrian access along Macalla Road at any time during the period October 13, 2020 through April 2021.

The Vista Point facilities will be OPEN for use from sunrise to sunset for pedestrians.

About the Southgate Road Realignment Project:

The Southgate Road Realignment Project will realign Yerba Buena Island's Southgate Road, the critical local connection  between the I-80 westbound and eastbound on- and off-ramps, and reconstruct/ reopen the I-80 eastbound off-ramp to Yerba Buena Island.

This project is part of a larger effort to replace and retrofit key roads and on- and off-ramps that connect the I-80 (the highway on the Bay Bridge) and Yerba Buena Island. The San Francisco Transportation Authority (SFCTA) is working jointly with Caltrans, the Bay Area Toll Authority (BATA) and the Treasure Island Development Authority (TIDA) on this effort.  View the Southgate Road Realignment Project website.
