In 2018, Caltrans announced plans to extend the carpool lane along I-80 from Solano County to Sacramento County, which includes plans to widen the causeway to four lanes in each direction.
The proposed widening would not start until at least 2024, and the project is estimated to cost $800 million.
One proposed alternative would use the extra lane as a toll lane.
