>Automobile traffic increased dramatically in the ensuing decades of the bridge's opening. This, among other things, resulted in the Key Systems decline, and by the 1960s having rails on the bridge had become obsolete and a detriment to traffic, as they carried nothing on them. Work began on removing the tracks in October 1963. After the work was completed, the Bay Bridge was reconfigured with five lanes of westbound traffic on the upper deck and five lanes of eastbound traffic on the lower deck. The Key System originally planned to end train operations in 1948 when it replaced its streetcars with buses, but Caltrans did not approve of this. Trucks had their ban lifted and were allowed on the top deck for the first time. Due to this, the upper deck was retrofitted to handle the increased loads, with understringers added and prestressing added to the bottom of the floor beams. This retrofit is still in place today, and is visible to Eastbound traffic on the western span.
>In current times, there have been attempts to restore rail service to the bridge, but none were successful. A study released in 2000 estimated the cost of restoring rail service across the bridge at up to $8 billion ($14.6 billion in 2024).
