The first phase of construction is utility relocation. Relocation is necessary to maintain access to these underground utilities with the addition of the future, center-running track. Design is also underway and will be completed, in order to further advance construction, in 2013.

The 3.1-mile Central Mesa extension will travel east on Main Street from the current end-of-line at Sycamore, through downtown Mesa to Mesa Drive. It will consist of four stations and a park-and-ride lot. The project will be built using a mix of regional Proposition 400 funds and federal grant dollars by late 2015/early 2016.
