Road Works: Road Traffic Control
The question
To ask the Secretary of State for Transport, what assessment her Department has made of the potential merits of promoting zipper merging at roadworks to reduce congestion and improve traffic flow.
Answered by Simon Lightwood
The Department for Transport works closely with local authorities to encourage effective traffic management during highway works, ensuring disruption to road users is kept to a minimum. Local authorities are responsible for determining the most appropriate traffic management plan as part of the permit conditions for the work, which may include measures such as zipper merging.
National Highways who maintain and operate the Strategic Road Network are always looking at ways to keep traffic flowing better during roadworks. This includes keeping the maximum number of lanes open at all busy times and carrying out the vast majority of work requiring extra restrictions overnight or at the weekend when traffic flows are lowest. National Highways has also increased the speed limit through most roadworks from 50mph to 60mph and is using more contraflows on its schemes, which can reduce the need for closures.
