There is a somewhat comparable project in the planning stages in Detroit - removing I-375, a 1.06 mile interstate spur into the heart of Detroit.

"In 1964, the I-375 freeway officially opened, connecting I-75 to Jefferson Ave., making Black Bottom a community of Detroit’s past.

Now, local and state officials are looking to reimagine one of America’s shortest interstate highways.

The Michigan Department of Transportation (MDOT) announced plans to demolish the controversial interstate and pave a new boulevard and business district for the one-mile stretch.

The $330 million project will create a six-lane boulevard that will include bike lanes, pedestrian paths, and green spaces."

A big part of that cost includes changes to I-75, which would not apply here,

Interesting. Yeah, in addition to no I-75 comp costs, my proposed design is only 4 lanes of traffic.

But it would be very interesting for a planning firm to put together a real budget for 147 based on more than my SWAG (scientific wild ass guess).

This is a very interesting comp project, though.
