The Highways Agency will shortly be carrying out essential safety improvements on the Tinsley Viaduct upper deck which carries the M1 between junction 34 north and junction 34 south near Sheffield, South Yorkshire.
Work to replace the existing central reservation safety barrier with a lightweight, high containment steel barrier will begin on 3 March and will last until September.
Highways Agency project manager, Tim Calvert, said:
The new barriers will improve safety on the M1 in South Yorkshire. This is a specialist engineering scheme which will take six months to complete. The new barrier units need to precisely positioned on the viaduct and only a small number of sections can be positioned at a time. In addition, essential central reservation concrete repairs, waterproofing and drainage renewal work will also be carried out.
During the work we advise road users to plan their journeys to avoid delays. Safety is our top priority and for the safety of road users and road workers we encourage all drivers to drive carefully through the roadworks, keeping within the speed limit, and concentrating on the road ahead.
During the work two lanes, of standard width, will be maintained over the viaduct and delays to drivers should be only slight. Lane two will be closed and drivers will use the hard shoulder and lane one. A free vehicle recovery service will be in place throughout the scheme and a 50mph speed limit, enforced by speed cameras, will be in operation.
To install and remove the traffic management, at the beginning and end of the scheme, it will be necessary to close the M1 between junction 34 north and junction 34 south, with signed diversion routes via Tinsley Viaduct lower deck.
The M1 junction 33 northbound entry slip road and the M1 junction 34 north and southbound exit slip roads will also be closed over the same weekends, with signed diversion routes in place.
