If any city or county contributes at least 33 percent of the estimated cost of any soundwall project included for the first time in the state transportation improvement program in 1992 or in subsequent years, that project shall be given priority over all other soundwall projects to be included for the first time in that state transportation improvement program. If, due to the accelerated priority given a project by this section, two or more projects each qualify for the highest priority, the relative ranking between the two projects shall be determined on the basis of their relative ranking prior to being accelerated.
