many countries suffered from road and motorway closures. in the united kingdom, the major motorways m1, m6 and m18 were closed in several places, as well as the m25 ring road around london and a number of other motorways. bridges including the m6 thelwall viaduct in warrington, the m25 dartford crossing in london and the m1 tinsley viaduct in sheffield were closed due to high winds. all pennine passes were closed. closures were largely due to the toppling of multiple high-sided vehicles. other motorways were affected by significant delays. long queues developed around blackspots, in particular replacement crossings of the manchester ship canal including routes through warrington and over the runcorn bridge.
