The I-15 Corridor System Master Plan is a summary document of a series of technical studies conducted by the I-15 Mobility Alliance that includes a long-range multimodal plan and a vision for development of facilities along the corridor. The Master Plan tells a story of the importance of the corridor and the challenges facing it, and outlines an approach for addressing these challenges, including multi-jurisdictional and interest group collaboration.
