A27/Worthing and Lancing Improvements

The Worthing and Lancing Improvements is part of the RIS1 A27 schemes. In total there was 4 schemes ranging from full bypasses to junction improvements. Worthing and Lancing was given a budget of £50-£100 million for the RIS1 period, which limited the options to on-line options, in 2023 the proposed scheme was reduced to 3 junctions with a budget of about £20m . This is because it is planned for these changes to be interim solution before an off-line route to be constructed around or under Worthing and Lancing which would not be delivered until 2040 at the earliest. Except from Arundel. Worthing and Lancing are the only part of the A27 that are single carriageway from the Fareham to Lewes, which are 60 miles apart.

2017 RIS 1 Scheme

Options considered

Only option 1 was taken to public consultation as the other ones were well in excess of budget or poor value for money.

Option 1

Junction improvements, retaining single carriageway, with direct accesses onto the A27.

Option 2

New Flyovers/Underpasses at Junctions, retaining single carriageway, with direct access to the A27.

This would have kept the A27 a single carriageway, however at some of the junctions it would have got flyovers/underpasses. Direct frontages to properties would have been kept onto the A27. This was discarded due to being in excess of budget.

Option 3

Junction improvements, upgrading to a dual carriageway, with direct access to the A27

This would have seen the A27 becoming a normal urban width dual carriageway, with the junctions being retained at-grade and properties having direct access to the road. It was estimated to of costed £274 million and a C2B ratio of 0.57, so poor value for money.

Option 3a

Junction improvements, upgrading to a narrow dual carriageway, with direct access to the A27

This is similar to option 3, however would be a narrow dual carriageway. It was estimated to of costed £238 million and a C2B ratio of 0.52, so poor value for money.

Option 4

New Flyovers/Underpasses at Junctions, upgrading to a dual carriageway, with direct access to the A27.

Similar to Option 2, however built as a dual carriageway. This was discarded due to being in excess of budget.

Option 5

New Flyovers/Underpasses at Junctions, upgrading to a dual carriageway, with no direct access to the A27.

Similar to Option 4, however properties would not have direct access onto the A27, this would also require service roads for those frontage properties. The option is ultimately plugging the dual carriageway gap in the A27, by putting the dual carriageway through the towns. This was discarded due to being in excess of budget.

Hybrid

This option is a mixture of junction improvements, some would be GSJ, and parts would become Dual Carriageway. Estimated cost £250 to £350 million, disregarded due to cost.

Works to take place

Junction 1 (Durrington Hill/Salvington Hill)

The existing priority junctions would be converted to a traffic-signal controlled, crossroad junction. Approaches may be widened to accommodate 2-lane approaches.

Junction 2 (Offington Corner - A24)

The existing roundabout would be converted to a traffic-signal controlled, crossroad junction. All approaches and some exits would be widened to accommodate extra slip roads and lanes.

Junction 3 (Grove Lodge - A24)

The approaches would be widened to accommodate two lanes of A27 traffic through the junction.

Junction 4 (Lyons Farm Retail Park)

The existing junctions would be widened to accommodate more lanes, and new turning arrangements will be created at both junctions.

Junction 5 (Busticle Lane/Halewick Junction)

A new traffic-signal controlled junction would be provided to the west of the existing junction, with access to and from Halewick Lane.

Junction 6 (Manor Road Roundabout) =

Existing junction approaches would be widened and the existing roundabout converted to a new traffic-signal controlled junction and a new traffic-signal controlled junction with Manor Road east of the existing junction.

2023 Scheme

The 2023 Scheme was subjected to consultation in February & March 2023 for delivery in 2025-2027. Three junctions are proposed to be modified, along with some alterations to other roads. It is costed at £20m and only targets junctions in Worthing with no changes to Lancing.

Offinton Corner - A24

The existing roundabout would be retained, but fully signalised with controlled crossings across all arms. Approaches and exits would be widened and Goodwood Road (residential road) would have its access to the roundabout closed.

Grove Lodge - A24)

The roundabout would have minor widening to increase capacity through the junction. A new controlled crossing would be provided across the Southern Arm of the roundabout

Lyons Farm Retail Park

Through lanes through the junction would be increased to 3 from 2, with minor other changes to the junctions

Upper Brighton Road

To minimise rat running, a section of Upper Brighton Road would be made one-way with a cycle contraflow lane
