Recently Completed Technical AnalysisRecently Completed Technical Analysis

Environmental– Biological Resources– Wetlands– Historical/Cultural– Hazardous Materials– Soils– Air Quality– Noise

Transportation– Transportation Analysis of Alternatives– Conceptual Level Design and Cost Estimates

Preliminary Cost EstimatesPreliminary Cost Estimates

Total costs (Public Project Scenario)– AT2 - $156 Million– AT6 - $154 Million– AS10a - $138 Million

Public costs likely less due to development related right-of-way dedications and roadway construction.
