Transit planners say it could take as much as $550 million to complete the troubled Southwest light-rail line — already the state's most expensive public works project with a potential total cost of $2.75 billion.
But where will the Metropolitan Council and other funders dig up a half-billion dollars to get the job done?
Met Council Chair Charlie Zelle says the cash needed to complete the 14.5-mile line between Minneapolis and Eden Prairie likely will come from different sources, including the federal government and Hennepin County.
But there isn't a detailed roadmap for backfilling the Southwest project's immense shortfall.
"We are committed to finding a solution, but the total puzzle has not been solved yet," Zelle said in an interview. "I don't think there's any shortage in commitment because [Southwest] is just too important for the region."
Hennepin County has already contributed more than $1 billion — about 90% of the local share — to help build the Southwest line, which will operate entirely within the county's borders.
But County Board Chair Marion Greene indicated in a statement that others need to open their wallets as well.
"We cannot cover these additional cost increases alone," Greene said. "It is not tenable for Hennepin County taxpayers to continue to be solely responsible for completing the largest infrastructure project in Minnesota history. It's time for other partners to step forward with a comprehensive funding solution that acknowledges the statewide significance of this project."
