State management: funds; Michigan mobility trust fund; create. Amends 2000 PA 489 (MCL 12.251 - 12.262) by adding sec. 4a. TIE BAR WITH: SB 0559'23, SB 0562'23, HB 5769'24

This bill creates a new Michigan Mobility Trust Fund within the state treasury to support transportation projects. It allows the state treasurer to accept money from various sources, including existing tax revenues, and directs that all interest earned on these investments be added to the fund. Money in the fund will not be lost at the end of each fiscal year but will remain available for future use. The bill designates the Transformational Projects Authority as the administrator responsible for auditing and spending the fund, but only after a specific appropriation is made. This legislation does not take effect unless several other related bills are also passed by the legislature.
