Our testimony today will focus on our work that parallels several issues to be considered by this Subcommittee. In summary, our work to date has shown that: (1) Increased funding will be needed for the Interstate 4R Program. (2) Projected Highway Trust Fund revenues are expected to exceed authorized commitment levels. (3) Tolls are a viable, alternative revenue source. (4) The Combined Road Plan demonstration block grant is allowing states increased flexibility to target spending to their priority needs. (5) State highway laws vary in the degree to which they parallel federal statutes.
