Alternatives Retained: Eight Lane Managed Build Alternative
9
• No specific operational scenarios identified at this stage
• To establish a sample range of travel demand conditions, the study considers: • High Occupancy Vehicle (HOV Lanes) • High Occupancy Toll (HOT Lanes) • All tolled
• HOV and All Tolled fit within the footprint of the Eight Lane Build Alternative
• If a specific tolling scenario is identified, additional environmental analysis may be required

Planning Level Cost Estimates
16
Bridge Costs (millions) Alternative 95-foot Bridge 135-foot Bridge Eight Lane Build Alternative $405 $635 Eight Lane Build – Managed Alternative $425 $670
Total Construction Cost (billions) Alternative 95-foot Bridge 135-foot Bridge Eight Lane Build Alternative $1.86 $2.22 Eight Lane Build – Managed Alternative $1.92 $2.30
Notes: 1) Planning Level Cost Estimates in 2013 dollars 2) Increased cost for managed lanes associated with additional pavement necessary to provide four-foot divider between managed lanes in each direction
