Since the latest patch you can no longer walk/run over at least one of the bridges in T2A. It looks as though the bridge was raised slighty. You can however teleport onto the bridge and walk off. It is located to the East of Delucia Felucca ... heading south to north, it is the second bridge from the bottom of map. Tried with couple different characters ... tried closing and reopening client ... don't think that it is just me. This was on Baja ... not sure if it's affecting other shards as well. PS - I did send to UO Bugs just in case.
