sinkhole appears on A26 in Kent
Homes evacuated after sinkhole appears on A26 in Kent
Witnesses described a police car overtaking vehicles and blocking the A26, in Kent, just before part of the road collapsed into a void.
Motorists said they heard a "crunching sound" before the 2m (6ft)-wide sinkhole appeared on Monday evening.
Work to repair the void, which could extend for up to 20m (65ft) underground, is likely to take weeks.
The bottom of a bus hit the dipping tarmac and made a slight crunching sound which is when we knew the road definitely wasn't safe.
