Without more money — at least $12 billion over the next 20 years — Minnesota's 12,000 miles of roads and bridges will continue to deteriorate, traffic jams will worsen and the effects will be far-ranging, according to an updated assessment of transit needs by the Minnesota Department of Transportation, or MnDOT.
Despite plans to spend $18 billion over the next two decades on transportation projects, $30 billion is required to meet the needs identified in the 20-year Minnesota State Highway Investment Plan, known as MnSHIP, released this week by the agency.
And those needs come at a time when several factors are conspiring to drive down the state revenue sources that are constitutionally dedicated to fund bridges and highways.
The plan, which is updated every four years, will help frame the debate for transportation funding in the upcoming session of the Legislature, which convenes Feb. 25. Bonding and transportation issues are expected to dominate the agenda.
"We're very concerned when we look at the money that's going to be available and the needs that we have, and are going to have," said Margaret Donahoe, executive director of the Minnesota Transportation Alliance, a coalition of groups that advocate for transit projects.
"It's really just a maintenance and preservation plan — and it won't even do a good job of that."
The plan acknowledges that, based on revenues, MnDOT won't meet all of its goals over the course of the next two decades. "The number of roads and bridges in poor condition will more than double and perhaps even triple within 20 years," the plan says.
It lays out dozens of highway and bridge projects across the state through the year 2019, and it projects what kinds of transportation investments will be made through 2033.
