Highways bosses reveal progress on roadworks which closed sliproad onto the A1(M) at Doncaster

Workmen are removing the old steel central reservation barrier along that motorway section of the A1, replacing it with 4,600 metres of concrete safety barrier and 370 metres of steel barrier protecting bridge supports with 1,550 metres of new central reservation drainage.

Today the organisation Tweeted: “We’ve removed 3,000 metres of steel safety barrier and posts on the A1 Doncaster and stripped off 75 per cent of the 2,500m of topsoil from the central reservation.

"We’ve also started excavation work for the foundation of the new concrete safety barrier.”

Narrow lanes are in place on the A1(M) between junctions 35 and 37 with a 40mph speed restriction so barrier work can be completed during the day (8am until 6pm).

As a result the northbound entry slip road from Wadworth roundabout (M18 southbound to A1(M) northbound) has been closed for the safety of drivers because officials feel there isn’t enough room for traffic to merge into the narrow lanes as well as traffic joining the A1(M) using the free-flow link.

Drivers are being diverted down to junction 34 at Blyth to then travel northbound. This will be in place until the narrow lanes are removed in November.

There will also be a number of overnight closures for deliveries and also to lift the precast permanent barriers into place.
