Guy Fawkes diversions

On 5 November Midsummer Common (Cambridge) is the scene of a huge Guy Fawkes Bonfire. Some of the nearby roads will be closed from 6.30 to 8.30 pm and this will mean that buses have to be diverted.

The A will go round by East Road and Elizabeth way, and won't be able to call at New Square. However, the notice says it won't call at Victoria Avenue - which it doesn't anyway.
I was curious to note that the diversion route doesn't simply cut straight from Elizabeth Way to Milton Road, but heads along Chesterton Lane to Staples Corner.

The B  towards St Ives will go via Hobson Street and King Street, skipping New Square. The notice  (pictured above) says it won't call at Jesus Lane either, although the map shows it passing the Jesus Lane bus stop.

The B from St Ives will reach the bus station via the Backs, Silver Street and Downing Street, and won't call at Round Church Street or New Square.
