HARTFORD, Conn. (AP) Senate Democratic leaders say a mid-year, budget-cutting plan up for a vote Tuesday begins the process of closing the Connecticut Juvenile Training School in Middletown and the Southbury Training School.

While the proposal includes $350 million in cuts to cover the shortfall in this year's $20 billion budget, lawmakers said Monday it also restores some reductions already made by Gov. Dannel P. Malloy to hospitals and social service agencies.

The plan also calls for creating through a separate bill a so-called ``lock-box'' to prevent transportation revenue from being spent on other programs. Ultimately, it will require voters to approve an amendment to Connecticut's constitution.

Lawmakers are returning Tuesday for a special session.

The Middletown facility is a juvenile detention center and the Southbury Training School serves people with profound developmental disabilities.
