Point (Marin County). The combined project, now headed by Oscar Klatt for the American Toll Bridge Company, received approval for the routing from then-Secretary of War Good in May 1929, although vertical and horizontal clearances for the proposed bridge were not fully established at the time. In November 1929, vertical clearance had been increased to to satisfy Navy requirements. The construction permit was issued in February 1930. Klatt's 1929 bridge was dormant for nearly a decade following the issuance of a construction permit in 1930. An extension was filed in 1938 to allow construction to start as late as February 1942, and fresh plans for a bridge district to facilitate financing were announced in 1939. In 1947, interest was revived in bridging Marin and Contra Costa Counties. Tomasini's San Francisco–Alameda–Marin crossings A third bridge was proposed in late 1927 by the enigmatic T.A. Tomasini. Tomasini's 1927 bridge called for two lanes of automobile traffic straddling a central rail line from San Pedro Hill (Marin) to San Pablo station (Contra Costa), a distance of over . In 1928, Tomasini presented a revised proposal for a bridge farther south than the other two bridges—spanning the water from Albany (in Alameda County) to Tiburon. The 1928 Tomasini Albany–Tiburon bridge was the longest of the three proposed bridges by a significant margin. The proposed Albany–Tiburon bridge would have been similar in concept to the 1967 San Mateo–Hayward Bridge, with a high-level western section approximately long transitioning to a low-level eastern causeway. The western section featured two spans to cross the navigation channels, with the western navigation span having a minimum vertical clearance of and the eastern navigation span having a minimum vertical clearance of . The navigation channels for the proposed Albany–Tiburon bridge were opposed by shipping interests, who wanted the channels to be wide instead. The cost of the longer spans required would have made the proposed Albany–Tiburon bridge impractical, and Tomasini argued that "any mariner who could not negotiate a bridge such as proposed should lose his license." Tomasini would later add a bridge spanning Richardson Bay in March 1928 from Sausalito to Belvedere to his proposal. The additional Sausalito–Belvedere bridge would have been long and wide with a lift span to allow the passage of large vessels, at an estimated cost of . Meanwhile, in April 1928 Tomasini recruited the prominent Ralph Modjeski to serve as the consulting head engineer for
