I'm not sure if it's been mentioned already, but the Brizzle Post is reporting that the recently-struck Gypsy Patch Lane Bridge will be shut for two years (or perhaps 344 days, they mention both periods of time) while the bridge is rebuilt to allow the Metrolbus under it. But they make no mention of whether rail services will be disrupted.

Just to be clear, this is not Hatchet Road bridge (the one by Parkway which was hit by a bus the other day) but Gypsy Patch Lane bridge, which is to the north-west on the South Wales line. I think this is another example of Metrobus money being used to fund a long-overdue road improvement - it'll be much safer for cyclists and pedestrians too.
