Additional drainage required

I found the drive across the bridge during the recent downpour on the 26th and 27th rather hardardous. Heading from Belconnon to Inner South I found the water on the road rather high. As I entered the bridge at 60km my wheels where drawn to the left. It is already a very narrow road. I can only imagine the difficulty this may cause if I was driving at a higher speed, in a wider vehicle and another car was heading cross the bridge from the opposite direction. It would be good if additional drainage can be installed (the other direction seems okay) to avoid a possible collision due to the lack of drainage installed by the Territory government.
