Cross-County Corridor

St. Louis, Missouri Metropolitan Area

(November 1996)

Description The East West Gateway Coordinating Council (EWGCC) and the Missouri Highway and Transportation Department are jointly studying alternatives for an 18-mile north-south corridor from the vicinity of I-270/I-170 near Lambert Airport south to Melville in the vicinity of I-270/I-55 in southeast St. Louis County. The study is also considering an east-west connection through Clayton, Missouri, to the existing MetroLink system. The Cross-County corridor traverses four other corridors in the St. Louis metropolitan area and is designed to facilitate north-south movements through the central portion of St. Louis County. This study will evaluate light rail, busway, highway, TSM, and No Build alternatives.

Preliminary cost estimates developed during system planning determined capital costs to be in the range of $269 million to $307 million (1989 dollars) for LRT.

Status FTA approved initiation of Alternatives Analysis/Major Investment Study (MIS) in September 1993. The study will produce information on the mobility improvements, cost effectiveness, environmental benefits, and operating efficiencies associated with each alternative. The MIS phase is expected to be completed in the Summer of 1997, when a preferred alternative and financing plan will be adopted.

Through FY 1997, Congress has appropriated $0.5 million for the study.
