Traffic lights are set to be installed on two busy roundabouts as part of plans to upgrade the A47.

The Vauxhall roundabout in Great Yarmouth will be controlled by signals and there will also be changes to the Gapton Hall roundabout as part of a £300m scheme to upgrade the major trunk road.

The news comes as a large banner was unfurled and displayed on the side of a footbridge near Gapton Hall bemoaning Great Yarmouth's traffic woes.

A hoarding was strapped to the side of a footbridge over the former A12.

It reads: 'Fed up with Gapton Hall traffic? Improve Gapton Hall roundabout. Stop the misery. What are GYBC and NCC doing about it?' The poster points to Great Yarmouth Borough Council and Norfolk County Council for a solution, however spokespeople for both local authorities pointed out that as a major trunk route, the A47 is managed by Highways England, which is controlled by the government.

At the Vauxhall junction, at the start of the Acle Straight, a larger roundabout will be built.

The bridge over the railway line will be widened to accommodate the widening of A47 from the southern approach.

There will be safety upgrades and possible improvements for pedestrians and cyclists.

At Gapton Hall a full set of traffic lights will be installed and people on foot or bike could also benefit from improvements.

The notorious bottleneck between Blofield and North Burlingham will also be upgraded from a single to a dual carriageway, following an alignment just south of the current road.

A new slip road at the Thickthorn interchange will mean drivers heading to or from Great Yarmouth will be able to avoid the roundabout junction with the A11, which is prone to congestion.

A group called the A47 Alliance, made up of representatives from local government and business, is now pushing for the Acle Straight to be dualled, and is hoping for secure cash in the next funding period.
