Having been advised that Orams Road overbridge in Manukau City is going to be closed for several weeks due to being struck from underneath by an overheight load (eyeroll!), I went hunting for a reference to post a link to someone (NZ Police's website being broken as I write this!) - Google found me this classic example from Transit New Zealand: Auckland Highway Info.
Makes you wonder if the person responsible for generating the content on this page has ever actually been subject to peer review. Sigh!
