When

No alerts between these times. If a bridge is still closed when they end, you'll hear then. If a bridge you heard was closed reopens overnight, you'll hear that at the end too. With rush hours, this only applies at weekends.

Tell me when

Closures nobody planned, such as high winds or a crash. Planned works count too if they start more than 30 minutes early or finish more than 30 minutes late.

When a closure we told you about ends. If that's outside your times, we tell you when your times start.

A reminder at 6pm the day before, if the works fall within your times. Then a message when the bridge reopens after the works, if that's within your times.
