UPDATED plans to remodel four of Swindon’s busiest roundabouts will be unveiled at two drop-in consultation sessions – but the project has been delayed by a year due to important sewer works.

Swindon Council’s estimated £10.7m scheme, which aims to reduce congestion and boost the local economy, will see four junctions on Great Western Way improved over a four year period. It will be paid for entirely from Section 106 money, provided by developers The work was supposed to start with Bruce Street Bridges this autumn, followed by Transfer Bridges, North Star and Cockleberry, but Transfer Bridges will now go first, followed by Bruce Street Bridges and then the other two junctions.

A spokesman said this was necessary as Thames Water planned to install a massive sewer pipe in the Bruce Street Bridges area, and this would delay the start of the project until October next year as there was still planning work to do on the designs for Transfer Bridges.

The council is holding two drop-in sessions to update and consult residents on the final scheme for Bruce Street Bridges and a more detailed scheme for Transfer Bridges. Previous exhibitions were held in July and November 2011.

The consultations are at Even Swindon Community Centre, Jennings Street, tomorrow from 3-8pm, and Gorse Hill Comm-unity Centre, Chapel Stwapreet, on December 6 from 3-8pm.

A spokesman said: “As Swindon continues to grow and develop, pressure on its transport system increases.

“Infrastructure improvements are currently underway in the town centre that will pave the way for redevelopment and reduce the amount of through traffic travelling to other destinations. Improvements to the efficiency of the wider network will be required to cater for these changes.

“The Great Western Way highway improvements scheme will seek to address these changes through targeted improvements to key junctions along this corridor.”

Under the current plans, Transfer Bridges will be a traffic-controlled “hamburger” junction, with a special route through the centre of the roundabout for motorists turning right out of Great Western Way, towards County Road.

Two concepts for Bruce Street Bridges were on display at a previous exhibition at the Oasis, and one final design has been created. Both involved bulldozing the four roundabouts and replacing them with a single one. The final plan does not have traffic lights, as proposed earlier, but features three lanes all the way around.

Designs for the other two roundabouts are still at the early stages and are expected to be affected by the Oasis leisure centre revamp.
