You can ride a bike across the eastern side of the Bay Bridge from Oakland as far as Yerba Buena island only. As the Bay Bridge Trail bike path runs along the new east span only, at present you cannot ride all the way across the bridge between Oakland and San Francisco. The bridge cycle path is open daily from 6 am to 9 pm, with access points opposite the IKEA store at Shellmound Street in Emeryville, and at the Bridge Yard building at 210 Burma Road in Oakland, where parking is available.
