Before the department commences the construction of any state highway or of any bridge, viaduct, conduit, pipe, trestle, or other obstruction in connection therewith across any cove, bay, or inlet of the ocean in this state, the department shall submit the plans of the proposed project, insofar as they might affect the use of such cove, bay, or inlet as a small boat harbor, to the Department of Boating and Waterways and shall consider any suggestions made with respect to the integration of the proposed highway project with any proposed plan for the development of a small boat harbor.
