Let's call it 850 MJ, or over 200 lbs of TNT in bomb form. units says it's 1693.7798 megaJ and 809.64615 lb tnt -- quite a lot of energy to dissipate. Given the cost of the bridge and the impact its loss is having / will have on commerce, constructing a bollard sufficient for that is quite justified, as well as changes to policies (such as not requiring tugs or other helps before getting past the bridge).
