Ensures the bridge has sufficient strength to withstand the statistically maximum load combinations it will experience over its design life.

: For the 5th edition, AASHTO made a strategic decision to not release an SI (Metric) units version . This edition, and all future editions, are published exclusively using Customary U.S. units (feet, pounds, kips, etc.). and all future editions

Many bridges spanning highways and waterways today were engineered using the 5th Edition or its immediate interim revisions. Engineers evaluating or retrofitting existing infrastructure frequently reference this specific edition to understand the original design intent.

Many structural engineering software packages still retain the 2010 AASHTO engine options to allow users to replicate older calculation sets accurately.
