1.1 BACKGROUND Adequate road infrastructure is fundamental for the economy of both developing and matured nations worldwide.

In a geographical context like Peru, with part of its population located in rural areas, roads are important for the integration and interconnection of the country. In cities with higher density it is important for roads and bridges to keep traffic flowing. Traffic delays cost billions in lost man hours, goods can be late to market and products late to port causing havoc on a nations productivity and economy. For this reason,among others it is very important that the road remains in good condition.

In many cases, bridges are the most vulnerable component of the transportation system and to apply a metaphor, a chain is not stronger than its weakest link; bridges are often the element that are the most critical to the continuity of the transportation system. The national highway systems of most developed country are ageing. Older structures have not been maintained properly and many of them average over 50yrs old.

According to the US 2017 Infrastructure Report Card "The U.S. has 614,387 bridges, almost four in 10 of which are 50 years or older. 56,007 — 9.1% — of the nation’s bridges were structurally deficient in 2016, and on average there were 188 million trips across a structurally deficient bridge each day. "

The condition of the bridges of the Road Network of Peru also varies considerably. Many structures again exceed more than fifty years of use and generally suffer damage due to lack of proper maintenance,more than by its antiquity. Some of the structures present a critical status with respect to its structural stability. Traffic assumes high levels of uncertainty associated with increasing risks. Their bridges are also affected by the influence of the environment, natural phenomena like earthquakes and floods, which causes their deterioration. The periodic climatic phenomenon known as "El Niño". El Nino is one of that major factors affecting conditions of the road network in Peru.

This phenomenon is repeated periodically causing major flooding washing away roads and bridges and causing economic hardship throughout the country.

In 1998 one of the strongest storms to date in Peru detroyed roads and bridges, power grids, schools and more. In 2018 in Genoa Italy a bridge collapsed killing dozens of people due to its age and deterioration. Updating bridge inspections worldwide is critical to maintaining infrastructures and saving lives.

1.0 INTRODUCTION

The Ministry of Transport and Communications is fully aware of the problems indicated here, and considered necessary, through the Road Infrastructure Management Policies to take measures to improve the condition of the roads, including bridges. Hence, the importance of the need to have a written instrument that guides inspections and serves as "GUIDE FOR INSPECTION OF BRIDGES ", allowing us to know the current status of those structures.

1.2 PURPOSE Establish a guide for the inspection of bridges in order to verify the state of the components of the same that allow the taking of decisions aimed at maintaining the continuity of the transit ability of the road infrastructure in an efficient and safe way.

1.3 OBJECTIVES The purpose of the Guide is to provide guidelines for conducting the inspection of the components of the bridges of the National System of Roads of Peru and other countries and municipalities through standardized technical procedures.

1.4 SCOPE This Directive shall be of compliance and mandatory application by executing agencies and / or managers of the corresponding road network, through the Engineers responsible for the Inspections of the Bridges.
