Abstract:

The National Tunnel Inspection Standards (NTIS) were published on July 13, 2015 and became effective on August 12, 2015. The regulation is part of a larger effort to implement a national tunnel inspection program for highway tunnels similar to the well-established program for highway bridges. The Office of Bridges and Structures has previously hosted webinars to share details in the regulation and the implementation timeline. Some State transportation departments and Federal agencies asked questions and express concerns during the webinars and afterwards. Several questions have centered on the definition of a tunnel and which types of structures are subject to the NTIS. This memo provides further guidance on different structure types that are or are not subject to the NTIS and can be used to guide efforts to inventory all highway tunnels by December 11, 2015 as required by the regulation. Guidance on how State transportation departments, federal agencies, and tribal governments should submit their preliminary inventory data will follow soon.
