Cal. Sts. & Hy. Code § 888.2
The department shall also incorporate nonmotorized transportation facilities in the design of freeways on the state highway system along corridors where nonmotorized facilities do not exist, upon a finding that the facilities would conform to the California Recreational Trails System Plan specified in Section 5070.7 of the Public Resources Code or upon a finding, following a public hearing, that the facilities would conform to the master plans of local agencies for the development of nonmotorized facilities and would not duplicate existing or proposed routes, and that community interests would be enhanced by the construction of the facilities.
The department shall establish an annual priority list of projects to be funded pursuant to this section, which shall primarily benefit bicyclists rather than other highway users.
