Transportation Improvement Program (TIP)

The Transportation Improvement Program (TIP) is a document of projects and programs to be either built or implemented in the next four years. It includes a list of multi-modal transportation projects, including highway, transit and bicycle. To be included in the TIP, projects must have committed funds from local, state, and federal sources.
