This document was developed in coordination with the National Tunnel Inspection Standards (NTIS) regulation 23 CFR 650 Subpart E and the Tunnel Operations, Maintenance, Inspection and Evaluation (TOMIE) Manual. It is intended to supplement the NTIS and provide the specifications for coding data required to be submitted to the National Tunnel Inventory (NTI). Data in the NTI will be used to meet legislative reporting requirements and provide tunnel owners, the Federal Highway Administration (FHWA) and the general public with information on the number and condition of the Nation’s tunnels.
