  • Northbound and Southbound – from 9pm to 5am on Saturday 7 August to Friday 13 August 2021 (6 nights)
  • Northbound and Southbound – from 10pm to 5am on Sunday 15 August to Friday 20 August 2021 (5 nights contingency)

Traffic Changes

Overhead variable messages and traffic control signs will alert road users of changes to traffic conditions.
