Structurally PA is fine, its the function thats horrid! PA was form before function and thats its downfall. Most of the Viaduct along 99th Street WONT need to be replaced, perhaps on the outside of the Viaducts where concrete has cracked exposing the steel rods will need replacement. As for the bridges, alot of is CONCRETE with steel whole spans need not replacement, but certain sections can be fixed. I've studied bridges and bridge design and the beauty of elevated structures and bridges of that era is that you can replace defective sections of the bridge rather than replace the entire span. They're very friendly! The engineers of past times understood the enormous costs of replacing entire structures and that it would be a horrible impact on services, so they built them extremely well and in a way that you can do replacements on defective areas as they are needed.Metro North showed you can build simple stations that are well built! Stations like Wakefield. simple station designs that are well prebuilt structures that are sound! As for trees, it'll cost millions of dollars, but its not something that would make or break whether a line gets built. |
