P10. Review Existing Freeway Agreement or Controlled Access Highway Agreement

The Freeway Agreement or the Controlled Access Highway Agreement documents the understanding between the Department and the local agency relating to the planned traffic circulation features of the proposed facility. It illustrates which streets may be closed or connected to the freeway or controlled access highway; which streets and roads may be separated from the freeway; it shows the location of frontage roads; and how streets may be relocated, extended or otherwise modified to maintain traffic circulation in relation to the freeway or controlled access highway. Locations of railroad and pedestrian structures, as well as those for other non-motorized facilities, should also be shown. Agreements are often executed many years before construction is anticipated and they form the basis for future planning, not only by the Department, but also by public and private interests in the community.

Sections 601-632 of Article 3, Chapter 2 of the Streets & Highways Code, identifies the termini for each highway route and any statutory relinquishments. Sections 253.1 - 253.8 of Article 2, Chapter 2 of the Code lists the highways that are in the California Freeway and Expressway System but the project engineer should review Route Adoption Maps and check for consistency with the most current RCR/TCR.

The project engineer must review existing agreements and determine if a new or revised agreement is required. It is also important to review the adjacent freeway agreements or controlled access highway agreements and evaluate design concept on a corridor basis. For example, legislation may have been enacted to relinquish the highway segment in the adjacent jurisdiction with a plan to ultimately rescind and relinquish the entire route as a local arterial. In this case, the intended design concept may not be a freeway. This information will be documented in the PID.

Superseding agreements are required for a major change, a new public road connection, a road closure, a minor change, or an accumulation of minor changes.

In addition to its importance for planning purposes, a current agreement is needed for regular acquisition of right of way and relinquishment of property back to local agencies.
