    The Mtentu Bridge is a multi span box girder bridge, currently under construction, spanning the Mtentu River, near Lundini in the Eastern Cape of South Africa. The Mtentu Bridge forms part of the N2 Wild Coast road (N2WC) project, which aims to improve the travel time between Durban and East London. Mtentu Bridge is scheduled to open as the highest bridge ever built in Africa with a deck height of approximately 223 meters. The massive central beam span of 260 meters will also be a record for the African continent among beam bridges and the 141 meter pier #9 will be also be the tallest on the. This project involves the construction of new road infrastructure to improve the transport link between the Eastern Cape and KwaZulu-Natal Provinces in South Africa The South African National Roads Agency Limited (SANRAL) is responsible for the implementation of this project. Its 260-meter main span will rank among the world's longest balanced cantilever designs. Imagine that stretching across a gorge near Lundini, a speck on the map that's now a construction hotspot.

    This code covers the welding requirements for welded bridges made from carbon and low-alloy constructional steels and designed to AASHTO or AREMA requirements. This 2025 edition contains dimensions in metric SI Units and U. Welding is a versatile, complex, and essential process that facilitates the use of a broad range of steel assemblies in transportation structures. Whether you're using MIG, TIG, or Stick welding, the balance between amperage, voltage, and travel speed affects the final weld, especially when working with thicker materials or precise. The American Association of State Highway and Transportation Officials recently issued 2024 interim revisions to its “AASHTO/AWS D1. 5:2020 Bridge Welding Code, 8th Edition. ” [Above image by AASHTO] Originally published in 2020, AASHTO's Bridge Welding Code guidebook includes welding. Let's say you're running a CV (Constant Voltage) machine at 18 volts and 150 amps on 3/16-inch mild steel. You decide you need more penetration, so you crank the wire feed speed.
