Transportation Concept Reports and Data Updates

The Transportation Concept Report (TCR) is a planning document that describes the Department's conceptual improvement options for a given transportation route or corridor. Considering reasonable financial constraints and projected travel demand over a 20-year planning period, the TCR considers transportation facility needs for each route or corridor. The TCR is a tool for implementing interregional and statewide continuity of the State's transportation network. The objective of a TCR is to have local, regional, and state consensus on route or corridor concepts, improvement goals, and planning strategies.

New reports will be posted as they are updated.
