MADISON, Wis. — Supporters of selling a 120-year-old state prison in Green Bay say developing the property near Lambeau Field would generate millions of dollars for the local economy.

But it doesn’t appear the Legislature intends to take quick action on the proposal.

The Republican-backed bill was heard by a state Senate committee on Thursday. The hearing comes at the same time the Legislature intends to study capacity needs at the state prison system, including whether to build new facilities and replace old ones.

Under the bill, a private entity would build and own the new Green Bay prison, allowing the home county and other jurisdictions to collect property taxes on it.

Bill sponsor Rep. Dave Steffan testified that a new prison would be more efficient and save the state $150 million a year.
