California Code, Streets and Highways Code - SHC § 887.6

Upon the request of a public agency, as defined by Section 6500 of the Government Code, the department may enter into an agreement with the agency for the construction and maintenance of nonmotorized transportation facilities which generally follow a state highway right-of-way where the department has determined that the facility will improve safety and convenience for bicyclists.

The department's contribution, if any, to the cost of constructing the nonmotorized facilities shall be based upon a finding that the traffic safety or capacity of the highway will be increased. The agreements may provide for the handling and accounting of funds, the acquisition or conveyance of right-of-way, maintenance, and any other phase of the project.
