Hi Leon, one thing I've noticed which may/may not be of interest, if the 'Merge Meshes' CPU optimisation option is ticked in CM/shader patch, the left-hand main support arc of the bridge disappears. Not sure if you use these various optimisations or not (or even CM/shader patch) but thought it worth mentioning just in case.

Also, and please don't hate me, I think you've tamed the kerb rumble a little
too much with the last update. Somewhere between the previous version and the current one might be a better sweet-spot maybe? Just my opinion of course, it's there to be ignored.
