Bridge Design Sachin Patel

The bridge that I have constructed costs around $322,122,00. Though this is not a very elegant and fancy bridge it is able to carry very heavy loads. The bottoms beams are 140*140 carbon steel rod solid bars, the inner of the bridge is 160*160*8 quenched and tempered steel hollow rods, with the middle being a combination of 140*140-170*170 carbon steel solid bars. The bridge I wanted to build was a a very strong bridge, so I had first constructed the bridge to be of all quenched and tempered steel, but that costs an upwards of 600K. I knew that was just to unrealistic, so i replaced all the outside beams with carbon steel sold bars that were of the same dimensions. but i kept most of the inside hollow quenched and tempered steel hollow rods, which gave me the most durability and cost effectiveness.
