Study Area

2

The study area is a buffer around the road corridor that includes all natural and physical resources that must be analyzed in the NEPA document. It does not imply right-of-way take or construction impact. Agenda Item 8

PURPOSE AND NEED

3

To improve capacity, congestion, lane continuity, and intermodal connections must be addressed

3

Improve Capacity Enhance Corridor Safety Improve Emergency Evacuation Address High Rise Bridge Improvements

To enhance corridor safety, roadway design and congestion must be addressed. To improve emergency evacuation, capacity, lane continuity, and roadway design must be addressed To address High Rise Bridge improvements, capacity and design deficiencies must be addressed. Agenda Item 8

  • 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

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
