Since the I-15 Mobility Alliance was established, the group has developed a partnership with over 90 public and private sector agencies; developed a comprehensive, multimodal master plan and subsequent update for the I-15 Corridor; and refreshed the list of prioritized Projects of Interregional Significance. Since 2011, over two dozen improvements on the current and past list of “Immediate Projects of Interregional Significance” have progressed in some fashion – from completion of environmental documentation to initiation of construction of some or all phases of the program – with eight successfully receiving federal discretionary funding.
