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
AREMA Standards for Cooper E-80 maximum loading
1917 Chinese-Built Cooper E-80 Locomotive on display in Green Bay, WI
• Can be used to
demonstrate future transit loading structure off existing foundations
• Provides staging areas
for operations • Provides additional
emergency space and traffic re-route
• Facilitate turnaround and refuge areas for large trucks and buses
Provide crossovers the full length of the individual spans at stations noted, versus only 50’ wide, and/or additional crossover west of bridge.
• Dredging and Pile Driving
• Critical to Schedule
• Migration of Atlantic and Short-Nosed Sturgeon (April – July)
• Piling Restrictions (April - July 5hr/day; Aug-March 12 hr/day)
