A19

Reconstruction of the existing Downhill Lane Junction, where the A19 and A1290 meet on the north-western edge of Sunderland, to provide more capacity for interchanging traffic.

The existing junction is a diamond interchange with a single bridge and four sliproads. A second bridge will be built and a roundabout constructed, converting the junction into a conventional roundabout interchange.

Widening of the existing A19 near Billingham to provide three lanes in each direction between Norton (at the interchange with the A1027) and Wynyard (at the interchange with the A689). At present this road is dual two lanes and suffers regular congestion. Planned housing developments in this area mean that additional capacity will be urgently required in the coming years.

The widening work will involve replacement of some bridge structures. The finished road will have three full-width lanes and will retain a 70mph speed limit.

Provision of a new dual two-lane flyover on a north-south alignment allowing the A19 to avoid the badly congested Testos Roundabout with the A184 near Sunderland.

The A19 will be slightly realigned around the junction to accommodate the new flyover.

The roundabout was originally laid out, when it was built, to allow for a flyover on an east-west line to carry the A184. This will not now be provided.

A scheme to reconstruct the interchange of the A19 and A1058 north-east of Newcastle upon Tyne. The aims of the scheme are to improve safety and reduce congestion at the junction, which is situated just to the north of the Tyne Tunnel. Since the tunnel was duplicated and made free-flow, this junction has become one of the few remaining impediments to traffic on the A19.

The Highways Agency's preferred option is to build a new cutting and associated slip-roads that will allow the A19 to pass freely through the junction under the existing A1058.

Construction of a second two-lane tunnel alongside the existing one at Jarrow. The new tunnel would take all southbound traffic, with the existing one converted to take all northbound traffic. This project would provide continuous dual carriageway from the A1(M) at Dishforth via Middlesbrough and Newcastle to the A1 at Wide Open.
