Stop by stop: tracing the route of the Central Corridor

This story begins a week-long series on the Central Corridor, which is planned to connect the two downtowns and the University of Minnesota with a new light-rail line.

The corridor would be 11 miles long and would connect destinations including the downtown areas of Minneapolis and St. Paul, the University of Minnesota East and West bank campuses, Midway industrial and commercial districts and the state capitol area.

End to end it would take almost 40 minutes to travel from one downtown area to another. Average weekday boardings are estimated at 43,330 riders. Stations would be located either in the center street median or on either side of the street, depending on the location and the space available in the street right-of-way.

Central would connect with Hiawatha light rail at grade, just east of the Downtown East/Metrodome station. It would run in the median of Third Street and Fourth Street, then travel along Washington Avenue. The West Bank station would be on Washington. Trains would cross the Washington Avenue Bridge to the East Bank campus. There would be an East Bank station in front of Coffman Union and a station in Stadium Village. The Washington Avenue route on the East Bank would travel in a tunnel. The route would connect with the U of M transitway at grade and extend along 29th Avenue SE to University Avenue. Prospect Park would have a station on 29th Street SE.

The route would extend along University from 29th Street to Robert Street. Stations would be located at Westgate, Raymond Avenue, Fairview Avenue, Snelling Avenue, Lexington Parkway, Dale Street and Rice Street.

Train tracks would run along Robert Street to Columbus Street, then to Cedar and Fourth Street, ending at a station in front of the Union Depot. The Capitol East station would be on Columbus west of Robert Street, with 10th Street, Sixth Street and Fourth Street stations.

Although Central Corridor has never been closer to reality than it is today, the project still has many hurdles to clear before construction can begin. The preliminary engineering work, addressing project design questions, should start in late spring or summer 2006 and will take about two years, as countless details of Central Corridor light rail construction are hammered out. Final design will take another year, followed by three years of construction.

Metropolitan Council Chair Peter Bell has already warned Central Corridor proponents that the project will have to be cut back. Its costs are a huge issue, already at $932 million. For projects to qualify for federal funding, they have to meet a cost-effectiveness index of $22.99 or lower. Central Corridor is at $24.84 now. Project costs and ridership are the key factors in determining a cost effectiveness index.

So how did the region’s second light rail project get this far? The Central Corridor, originally known as the Midway Corridor, has been on the drawing boards since the 1980s. The original route was to be built in the Interstate 94 median, with connecting buses stopping on freeway overpasses and riders using elevators and stairs to reach trains. Other proposed routes included Ayd Mill Road, Pierce Butler Route, Energy Park Drive, Minnehaha Avenue and the Burlington Northern Santa Fe (BNSF) railroad tracks that cross the Midway. University Avenue, today’s chosen route, was ruled out in large part because of concerns that businesses would lose on-street parking.

The I-94 route never mustered enough support at the state capitol to gain state (and needed federal matching) funds. Ramsey County shifted support in the mid-1990s from Central Corridor to the ill-fated Riverview Corridor as its top priority. Riverview, a high-speed busway connecting Maplewood Mall to Minneapolis-St. Paul International Airport and mall of America, was part of a proposed "transit triangle" with Hiawatha and Central corridors as its other legs. After Governor Tim Pawlenty took office he took $40 million of $44 million set aside for Riverview to address a state budget deficit, which essentially killed the project, although it remains in some long-range transit plans.

Tomorrow: Central Corridor finally on track, but questions remain
