In collaboration with the Treasure Island Development Authority, the $63.7 million project features an intricate design that will improve traveler safety for motorists, cyclists and pedestrians and enhance traffic circulation by:
- Relocating and re-designing Southgate Road and interchange, separating vehicle traffic heading to westbound and eastbound I-80/Bay Bridge lanes
- Continuing the dedicated bicycle and pedestrian path from the Yerba Buena Island Vista Point (at the western terminus of the Bay Bridge East Span Bike/Pedestrian path) to Treasure Island via Macalla Road
- Reconstructing the eastbound I-80 off-ramp to Yerba Buena Island with a design that optimizes traffic flow
- Ensuring that all truck turning movements are accommodated in the area.
