ABAG Post-Earthquake Transportation Disruption Maps and Information
	Related to Roads, Bridges, and Airports in the San Francisco Bay Region

However, we also have developed a TIPS page to aid families and businesses in dealing with these transportation closures.

ROAD CLOSURES IN EARTHQUAKES
ABAG estimates of number and location of ROAD CLOSURES in 18 future expected Bay Area earthquakes were last updated in April 2003. This estimates are consistent with the earthquake scenario probability information released by the U.S. Geological Survey in April 2003. The information includes tables, maps, and planning considerations.
In addition, the following REPORT EXCERPTS are available for free online. These excerpts have been modified to make them consistent with the April 2003 road closure estimates.

What Are We Predicting Will Happen To Our Transportation System in Future Earthquakes? Checklist for Planning Actions     Use ABAG's OnLine webstore to purchase the 1997 technical documentation, Riding Out Future Quakes - Pre-Earthquake Planning for Post-Earthquake Transportation System Recovery in the San Francisco Bay Region. Although the closure estimates are significantly different from 1997, and many estimates are significantly higher, the technical documentation and basis for these estimates has not changed significantly since the 1997 report.
AIRPORTS AND EARTHQUAKES
ABAG released a report on airports and Bay Area earthquakes in December 2000. The report, Don't Wing It!, features answers to important issues. (1) How vulnerable are airports? (2) What will we need from airports for emergency response and economic recovery? (3) Is there a role for other airports? The report also includes recommendations from a workshop held on October 10, 2000.

	Slide Presentation -- from ABAG's Subregional Workshops on Transportation Problems in Earthquakes in October and November, 1998. (Note that the number of road closures listed on these slides is slightly higher than those in the October 1997 report. This discrepancy is due to ABAG's use of Oct. 1998 information from Caltrans on bridge and overpass retrofit status, versus Oct. 1996 information used in the October 1997 report.)

	Link to BART's Seismic Retrofit Program - Because of the likelihood BART will be subject to a major earthquake, and to safeguard the public’s significant investment in the system, BART has initiated the Seismic Retrofit Program. The program will upgrade the original BART system operating facilities to ensure that they can return to operation shortly after a major earthquake. Facilities that are not directly related to operating BART trains (such as offices, shops and training facilities) will be upgraded to ensure safety for the public and BART employees. This will be accomplished by using the latest seismic standards to upgrade the structural integrity of vulnerable portions of the system.

ABAG's efforts to model road closures were funded by Caltrans, the U.S. Geological Survey, and ABAG. Our recent efforts to plan for these closures and to collect "Ideas for Action" have been funded by a creative partnership of public and private organizations, including the California Governor's Office of Emergency Services, ABAG, Pacific Gas and Electric Company and Pacific Bell.
