A measure calling for an in-depth audit of the Southwest light-rail line, a project riddled with cost overruns and delays, won approval Thursday in the Minnesota House.
The bill drew widespread bipartisan support and was passed 129-1.
It calls on the Legislative Auditor's office to conduct a special review of the state's most expensive public works project and sets aside $200,000 to pay for it. The Senate Finance Committee passed a companion bill Thursday.
The Metropolitan Council recently announced that the project would cost an additional $450 million to $550 million, bringing the total cost to between $2.65 billion and $2.75 billion.
The 14.5-mile line is about 60% complete and will link downtown Minneapolis to Eden Prairie by way of St. Louis Park, Hopkins and Minnetonka. Passenger service is expected to begin in 2027, about four years later than earlier planned.
"I think the situation is unprecedented; it's a very urgent matter," said Rep. Frank Hornstein, DFL-Minneapolis, one of the bill's sponsors.
Last summer, Hornstein and Sen. Scott Dibble, DFL-Minneapolis, asked the legislative auditor to review the project after a $200 million Hennepin County contingency fund was tapped to cover unexpected costs.
The legislative auditor released a memorandum in October that highlighted a "prolonged and significant" difference of opinion on construction issues between the Met Council and a major contractor.
