The off-ramp for Treasure Island and Yerba Buena Island is unusual in that it is on the left-hand side in the eastbound direction. This off ramp presents an unusual hazard – drivers must slow within the normal traffic flow and move into a very short off-ramp that ends in a short radius turn left turn; accordingly, a 15 MPH advisory is posted there. The turn has been further narrowed from its original design by the installation of crash pads on the island side. Eastbound and westbound on-ramps are on the usual right-hand side, but these do not have dedicated merge lanes, forcing drivers to await gaps in traffic and then accelerate from a stop sign to traffic speeds in a short distance. In 2016, a new on-ramp and off-ramp to Treasure Island were opened in the western direction on the right-hand side of the roadway, replacing the left-hand side off-ramp in that direction.
