SUMMARY

This Major Transportation Investment Analysis Report summarizes the work performed in Phases 1 and 2 of the St. Louis Cross-County Corridor Major Transportation Investment Analysis. This report summarizes the analysis of the transportation strategies considered and documents the decisions made by the Study Management Group regarding the strategies recommended to proceed into the next phase of project development in the Cross-County Corridor.

The report provides a brief summary of the Phase 1 study activities, outlining the principal problems identified and the methodologies employed in that process. It includes a brief summary of the Phase 1 screening process and the transportation strategies recommended by the Study Management Group to be advanced into the Phase 2 analysis.

A more detailed summary of the Phase 2 activities is presented, including a summary of the Phase 2 public involvement activities, the refinement and conceptual engineering of the discrete strategies developed in Phase 1 in each of the four subcorridors, and the combination of those discrete strategies into multimodal "strategy sets" covering the entire study area. These ten strategy sets are the final alternative solution packages, and cover a broad range of potential investment levels with varying combinations of highway and transit solutions.

The report documents the process used in comparative evaluation of the ten strategy sets, and describes the performance measures used for that evaluation. A matrix presenting 50 different performance measures for each of the strategy sets is included. The report also summarizes a possible weighting process for use by the Study Management Group to allow reduction of the evaluation process into a more manageable number of evaluation criteria. The report also presents comparative analyses of both the Strategy Sets and the Discrete Strategies evaluated during the course of this study. Finally, the document presents the recommendations approved by the Study Management Group and adopted by the East-West Gateway Coordinating Council's Board of Directors.

Included as a part of this report, but bound in a separate 11" x 17" document entitled Major Transportation Investment Analysis Report Exhibits, is a set of exhibits detailing the discrete strategies recommended in Phase 2 by the SMG and adopted by the EWGCC Board, shown on aerial photography base mapping at a scale of 1" = 400'.
