This monograph aimed to analyze the traffic conditions in the deviations caused by the works of the Taguatinga, DF tunnel. A stretch of approximately 1 km that makes up Avenida das Palmeiras was analyzed, in its two directions: Pistão Norte and Pistão Sul/Brasilia. The section in question has two traffic lanes, divided by a central median, and two traffic lanes per direction. Before becoming a detour, Avenida das Palmeiras received a smaller flow of light vehicles. However, with the works on the Taguatinga tunnel, there was a significant increase in the number N of vehicles, including heavy vehicle traffic, according to official sources from the Federal District Government. In the available methodology, an exploratory and descriptive bibliographic review will be found, supported by field research, and using continuous visual survey, Standard DNIT 008/2003 and DNIT 009/2003, Pavement Management System, Current Service Value, Pavement Management Manual, Measurement of Longitudinal Pavement Irregularity and SmartIRI software, supported by photographic records of the pavement. The data obtained allowed us to verify the existence of pathological manifestations with a high frequency of occurrence, classified as cracks, fissures, wheel tracks, pans, exudation, undulations, slips, sinks and patching, expected deformations, since the pavement project was made to meet a low traffic demand for vehicles circulation. Through the criteria established by the tools described in the methodology, the results of the subjective assessment characterize the pavement as “good”, demonstrating consistency with the results of the structural assessment, whose IRI value ranged from 3.31 to 3.59. Despite this characterization, it was found that there is still a need to carry out corrective maintenance in order to provide good traffic conditions, with comfort and safety to users who use Avenida das Palmeiras
