The tunnel stock info will also be obtainable in the annual report to Congress demanded by MAP-21. The tunnel stock info will allow FHWA to track and identify any patterns of tunnel deficiencies and facilitate repairs Get started Printed Webpage 41354by States to ensure the protection of the public.
