;Central Freeway
This all important freeway will start at Broadway just east of Van Ness Avenue. See Plates 5-1 and 5-2. The roadways will be depressed from Broadway to Clay Street at which point they will be carried on an elevated structure on a right-of-way of restricted width parallel with and between Van Ness Avenue and Polk Street. A connection to a portal in the center of Van Ness Avenue north of Broadway will be made by a short tunnel. A spur between Pine and Bush Streets will accommodate traffic to and from the downtown area. This spur will take advantage of topography to reduce grades for traffic which will be delivered to the existing street system near Hyde Street.
The route will swing to the southwest in the block between Eddy and Turk Streets, crossing Van Ness Avenue and continuing to a location in the block between Gough and Octavia Streets at Fulton Street. The route then extends southward to a location just south of Market Street providing space for the necessarily elaborate interchange with the Panhandle Freeway. This entire section will be elevated - largely on solid fill with gentle side slopes which will afford an opportunity for attractive landscaping.
From this point the Central Freeway will swing easterly as an elevated structure making connections with the Mission Freeway and utilizing the right-of-way now being acquired for 13th Street between Valencia and Folsom Streets. The route will then continue to interchange with the Bayshore Freeway south of Bryant Street and centered approximately on 9th Street. At this point the Central Freeway loses its identity as such, becoming an extension of the Bayshore Freeway to the approaches to the San Francisco Bay Bridge.
This great central artery constitutes the major feature of a grand circumferential distributor loop around the Metropolitan Traffic District. Completion of the loop involves the use of the Marginal Freeway from the bridge approaches to the vicinity of Market Street, the Embarcadero from this point to Broadway, and Broadway from the Embarcadero to Van Ness Avenue.
Normal weekday traffic on the several sections of the freeway system has been estimated at both 1947 and at 1970 traffic levels. Allocations of traffic have been made by detailed review and study of the trips between origins and destinations, at external points and in the numerous zones in San Francisco. These estimates are summarized in Plate II-10. The high economic value of the Central Freeway is shown by the fact that it will attract the greatest volume of traffic of any of the freeways in the system.
