The Merced County Association of Governments (MCAG) has prepared an amendment to the 2022 Regional Transportation Plan / Sustainable Communities Strategy (RTP/SCS). The 2022 RTP/SCS, adopted on August 18, 2022 by MCAG, included a list financially constrained improvement projects. Amendment No.1 is required to reflect additional passenger rail projects and revised phasing and modeling for various highway improvement projects. The total net change in funding for the passenger rail projects is $899 million over the 24-year period or between years 2022 and 2046 specifically related to the cost of new passenger rail projects. The additional cost of these passenger rail projects will be addressed by additional funding including Interregional Transportation Improvement Program (ITIP), Senate Bill (SB) 1 (TCEP, TIRCP, Congested Corridors, and other related funds), and other (PTA, SRA, Port and Freight, and other). The Amendment includes the listing of nineteen (19) regionally significant roadway projects, currently reflected in the 2022 RTP/SCS, includes two new modeled projects, and phasing and open-to-traffic changes to existing projects. Details are presented below.
