The 2020-2029 State Transportation Improvement Program comprises 1,718 projects — some in every county across the state — including 399 non-highway projects (aviation, public transit, rail, ferry and bicycle/pedestrian). Most were identified through a data-driven scoring approach called Strategic Prioritization.
Also included in the total are interstate maintenance, bridge, and safety projects selected under "alternate criteria." Alternate criteria projects undergo a separate prioritization process.
Below is a breakdown of the number of projects by mode.
