Here is a short overview of the most interesting part of the bridge:
SELF-ANCHORED SUSPENSION SPAN
If one single element bestows the status of world-class on the new Bay Bridge, it is the Self-Anchored Suspension (SAS) Span. This engineering marvel will be the world's largest SAS bridge (2,047 feet).
The SAS is not just another suspension bridge. Traditional main cable suspension bridges have twin cables with smaller suspender cables connected to them. These cables hold up the roadbed and are anchored to separate structures in the ground. While there will appear to be two main cables on the SAS, there is actually only one. This single cable is anchored within the eastern end of the roadway. The cable is carried over the tower and wraps around the two side-by-side decks at the western end.
The SAS, and the rest of the new East Span, is being built to the north of the existing bridge. By switching from the existing East Span's double-decks to side-by-side roadways, drivers will enjoy unencumbered and expansive views of the Bay Area as they pass beneath an angled canopy of suspension cables. The SAS, and Skyway, will feature a 15-foot-wide cantilevered bicycle and pedestrian path on the eastbound side of the bridge, so those traveling on foot or two wheels between Oakland and Yerba Buena Island (YBI) can enjoy those majestic views of the Bay as well.
The new SAS bridge echoes the existing towers of the West Span, as well as the towers on the Golden Gate Bridge. All vertical elements of the SAS – the tower, piers and lights – have been designed to emphasize its clean modern lines. Adding to its distinctiveness is the asymmetrical design. The bridge will have a longer forward span (east of the tower), which will provide a more gradual transition from the gently sloping Skyway, and will give the new East Span a unique silhouette. While the new East Span will have side-by-side decks, those decks will transition to a double-deck structure at YBI, to carry traffic through the YBI tunnel and onto the West Span.
The design features state-of-the-art seismic safety elements and will provide the East Span with a modern, streamlined appearance. Rising 525 feet above mean sea level and embedded in rock, the single-tower span is designed to withstand a massive earthquake. The single steel tower will be made up of four separate legs connected by shear link beams, which function in the same way as a fuse in an electrical circuit. These beams will absorb most of the impact from an earthquake, preventing damage to the tower legs. In addition, if one of the legs is damaged, the other legs will keep the bridge standing.

Concrete Bridge Practice Analysis, Design And Economics - 2nd Ed.
Book Summary of Concrete Bridge Practice: Analysis, Design And Enonomics
The second edition of this highly successful book is a complete reference on analysis, design and economics of concrete bridges. Meant for design engineers, contractors, their clients and field engineers, the book presents a practical and systematic methodology to enable quick and accurate design decisions. A step-by-step approach has been adopted throughout the text reflecting the order in which a practicing professional might proceed for designing a concrete bridge. The book contains more than 350 illustrations and photographs, tables and charts, and covers in detail topics such as: Structural analysis; Stability of foundations; Soil mechanics; Foundation design; Reinforced and Pre-stressed concrete design. The new edition has been considerably enhanced with additional chapters on: Estimating safe bearing capacity of soils for footings; Caissons and piles; Maintenance management system for highway bridges; Bridges distress reporting-A workman-like approach. With its absolutely professional and non-academic approach to designing bridges, giving the shortest and optimal paths to design decisions, this book would be indispensable to all design engineers.

Abstract.
The development of standardized timber bridge plans and specifications is a key element in improving design and construction practices. The bridge plans presented were developed as a cooperative effort between the USDA, Forest Service, Forest Product Laboratory (FPL), the University of Alabama, and Southern Pine Council....designing loads for AASHTO HS 20-44 and HS 25-44 vehicles, and two options for live-load deflection criteria.

Does anyone have CBIP Manual On Transmission Line Towers (Technical Report No. 9)?
Im sorry that I dont have any information about this publication except that it was published by the Central Board of Irrigation and Power (CBIP) of India. Would very much appreciate your share here.
HIGH PERFORMANCE CONCRETE STRUCTURAL DESIGNER’S GUIDE
High Performance Concrete Technology Delivery Team
Introducing . . . the Federal Highway Administration’s
HIGH PERFORMANCE CONCRETE TECHNOLOGY DELIVERY TEAM
Created to implement a mandate of the Intermodal Surface Transportation Efficiency Act of
1991 (ISTEA) legislation, the Federal Highway Administration’s (FHWA) High Performance
Concrete Technology Delivery Team (HPC TDT) motivated and helped State DOT’s to build
more economical and durable bridges using high performance concrete. The TDT, created in
1997, assisted 13 States in design and construction of HPC bridges. Hundreds of State, Federal and industry personnel were introduced to HPC technology at workshops and showcases planned by the TDT and hosted by participating DOT’s. Working with the American Association of State Highway and Transportation Officials (AASHTO) Lead States Team on HPC Implementation, the TDT influenced many additional State DOT’s to try HPC in their highway bridges.
By the time the ISTEA legislation expired, about 25 States had used HPC. Today, the TDT
continues to promote HPC and encourage states to build HPC bridges through the Innovative
Bridge Research & Construction Program (IBRCP) created under the current highway program of TEA-21. HPC is considered an innovative material and projects can be funded under the guidelines of the IBRCP.
Two primary factors led to the rejuvenation of the HPC TDT. In 1998, the FHWA created
Resource Center offices in Atlanta, Baltimore, Olympia Fields (IL), and San Francisco. These
Centers were staffed to bring training, technical expertise and technology transfer specialists
closer to state and local highway agencies. In addition, the TDT was being renewed with a
focus on field delivery of HPC technology. Accordingly, TDT members represent the FHWA
Resource Center; the Division Offices; the Agency’s Headquarters Offices of Bridge and
Pavement Technology; the Office of Infrastructure Research and Development; the Eastern
Federal Lands Highway Division; and various State DOT’s. Recognizing that earlier
technology delivery efforts were the result of key partnerships and coordination, the new TDT also includes representatives from academia and industry.
