Question to the Department for Transport:

To ask the Secretary of State for Transport, how many kilometres of life-expired steel barrier have been replaced with concrete barrier on the Strategic Road Network in each of the last four years excluding upgrades delivered through the Smart Motorways Programme and the Smart Motorways Alliance; and what her projection is for steel-to-concrete barrier replacement outside the smart motorway programme in 2025–26.

Through its renewals programme, National Highways has delivered 52.6 kilometres of concrete barrier over the last four years and are projecting to deliver a further 14 kilometres of concrete barrier in 2025-26. This is excluding upgrades delivered through the Smart Motorways Programme and Smart Motorways Alliance.
