The original problem of locating the EastBay approach system required by the Re-construction Finance Corporation, andlater adopted by the legislature as officialapproaches to the bridge, involved twofundamental considerations: 1. Tapping the East Bay area so as toserve the thousands of daily users of thebridge, who, through tolls, pay off the mil-lions of dollars invested in the project. ^ 45 ?

So locating the approach arterials that they would ultimately become portions ofState highway through routes.
