There was a serious accident in Catford about 11am at the junction by the library (apparently an elderly lady was knocked down and dragged under a lorry) closing Catford Rd between the main junction and Canadian Avenue. A lot of bus routes were diverted for hours. Having got off a 185 from Forest Hill in Catford about 2pm I then found I couldn't get home at 3.30pm! Had to get another bus into Lewisham to be able to pick up the 185/122 there but by the time I got to Lewisham found they had reopened the road (around 3.45pm) and so went all the way back through Catford again. Lost well over an hour of the afternoon sitting in traffic and waiting for buses plus extra bus fares! Although I appreciate the accident wasn't London Buses fault, their lack of communication with customers was as usual poor. No warning when we got off the bus the Catford we wouldn't be able to get back. Having been told to go to Lewisham to change onto the affected routes it was even more annoying that the drivers then chose to cut out Lewisham High St and used Molesworth St giving us a trek right through the Shopping Centre with heavy shopping! No London Buses staff at Lewisham to warn passengers buses were being diverted. I'd heard about the accident on the radio hours before but no mention of the disruption to buses.
