How to unlock the Financial Genius achievement in Bridge Constructor - Definitive Guide

Unlocking this achievement will also unlock Budget Master, Financially Talented and Financial Manager if you haven't already unlocked them.
While this is not possible for every bridge, there are several where this much disparity in price becomes doable. Each bridge has a maximum amount of money that you can spend. This trophy requires that you successfully drive both regular trucks across any bridge while having your cost be 25,000 (or more) below the maximum budget.
Wood and suspension cables (if available) are the best way to build for this trophy. Additionally, once you unlock tank trucks the budget is increased for most bridges. This trophy still only requires regular trucks but that increased budget can help you meet this goal. With that said, there are several places where you can acquire this trophy before unlocking tank trucks.
This trophy unlocks during the success screen and will stack with all of the lower cost trophies of this same type. If you are having trouble, here is an example of how to do this (saving 25,300).
The Ridge - Bridge 4
Starting budget: 33000 | Tank budget: 38000
Your budget will be dispalyed at the top of your screen and will show you how much you have currently spent. The goal here is to use as few materials as possible while still being able to support a truck. Using only wood or small amounts of steel cables is the goal here and there are several maps where a wooden only structure will allow a truck to cross while coming in way under budget. I strongly suggest referring to the guides athttps://www.bridgeconstructor.net/ as several of these will allow you to construct a bridge for more than 25,000 under budget so expect this to unlock naturally on your way to having all trucks cross every bridge.
