What do you mean by drainage structures.They have started doing preparatory draining and other mitigation construction along SR528 between Cocoa and Orlando, in preparation to start actual earthwork for the ROW. One major intersection on SR528 has been completely modified to grade separate the entry-exit ramps from the Brightline ROW. ROW work should begin mid year this year once the drainage structures have been put in place.
Does this mean temporary drainage to permit construction work? Or is there going to be some permanent drtainage system to keep the tracks dry? Isn't the normal way to build railroads across a virgin swamp usually to dump massive amounts of crushed rock to provide a stable foundation, which, once it has settled, doesn't need specific drainage? Crushed rock being pretty much self-draining.
Or are you talking more about diverting, protecting or accomodating existing drainage ditches that cross the future track bed? For example by building culverts?
