39 of 56 Recommendations Implemented $642 Million Implemented Cost Saving Design Criteria Constructability Schedule Staging Future Mass Transit Document Control QA/QC

Allow use of high performance steel >70ksi.

Allow use of high strength concrete >10ksi for segmental construction.

Define acceptable types of cable material and protection system for cable stays.

Provide design criteria including load combinations for stay cable and hanger replacement or loss.

Refine fire protection and water supply requirements.

Refine security requirements during construction and for new bridge operations.

• Accommodate heavy/light rail or bus

• Design future deck between structures

• Provide future loading in foundations, piers and cable stay structures, per standards
