Abandoned/Ruined Bridges

I Think It Would Be Cool To Have Abandoned/Ruined Bridges, Made Of Planks, Logs, Wood, Stairs, Fences, Fence Gates And Slabs. When The Bridges Are In Certain Biomes, The Materials Would Be The Biome's Tree Materials, (Example: Cherry Grove = Cherry Materials.) If The Biome Does Or Can Have More Than One Material Tree Or Log Like Blocks, There Will Be More Than One Of The Bridges Made Of More Than One Tree/Log Like Material In That Biome, Or Also Bridges Can Be Made With All Tree/Log Materials In That Biome. (The Bridges Will Most Likely Be In Rivers.)
