Legislative Response
  • 1997 SB 60 (Kopp)
  • Established Toll Bridge Seismic Retrofit Program
    (SRP)
  • Identified the five Bay Area State-owned toll
    bridges as seismically deficient and in need of
    retrofit or replacement
  • Established program budget of 2.6 billion
  • 2001 AB 1171 (Dutra)
  • Increased program budget to 5.1 billion
  • 2005 AB 144 (Hancock)
  • Established Toll Bridge Program Oversight
