Marvin Scroggins grew quiet as he stared at the interstate that replaced his childhood friends' homes 50 years ago, forcing them to leave the tight-knit Rondo community. He contemplated what it would mean to cover the cement gash of I-94 with a land bridge that could hold shops, homes and parkland.
Then the treasurer of Rondo Avenue Inc. gave a pragmatic answer: "I look at it as an economic development opportunity."
Interest about spanning parts of freeways in the Twin Cities isn't limited to nearby residents. State and federal transportation officials, business owners and developers are exploring the notion of "capping" several sections of freeways with wide swaths of land. The idea has been floated around the Twin Cities area from St. Paul to north Minneapolis to Edina.
Some view it as a way to add developable space in built-out areas. Others see public health benefits in controlling air and noise pollution. And, at least in St. Paul's former Rondo neighborhood, it could help heal the lingering pain I-94 left when it tore apart the historic African-American community.
The cost of building the land bridges could be tens or even hundreds of millions, but planners say the big idea is gaining traction.
Will investors step up?
"We've seen, in the last couple of years, a complete shift in thinking about this, from 'Oh, this is kind of a wacky idea,' to 'No, this solves many problems and it should happen,' " said Thomas Fisher, director of the University of Minnesota's Metropolitan Design Center.
As the Minnesota Department of Transportation prepares to replace aging infrastructure, officials are asking community members to think about other changes that could be made to freeways, I-94 project manager Brian Isaacson said.
Covering them with land bridges, also called lids or caps, has been a popular answer.
