Hamburger roundabout in Black Dam is off the menu

Basingstoke Gazette: Black Dam Roundabout Black Dam Roundabout

A MULTI-MILLION pound scheme to transform a busy Basingstoke roundabout and improve traffic flow has been altered.

The Government-backed £10million estimated project would have seen two-way traffic pass through the centre of the 40-year-old Black Dam Roundabout, connecting the M3 junction 6 slip road to the A339, and would have been Basingstoke’s first so-called hamburger roundabout.

But the Highways Agency has radically changed its original plan for two-way traffic and is now planning to direct four lanes of northbound traffic into the centre of the roundabout instead.

An additional two-lane arm is also set to be added to the roundabout to allow motorists travelling on the A30 to join the centre of the new roundabout, easing congestion for people going to the town centre and on the A339.

The scheme is also set to see the realignments and widening of all approaches, the installation of safety barriers, new traffic signs, signals and street lights.

The Highways Agency amended the original plans after staff carried out investigations into the scheme and decided the new layout will offer more benefits for motorists.

Construction work on the improved roundabout will begin in July – and it is expected to continue until March 2015.

The redevelopment of the busy roundabout was announced by the Government in 2012, as part of its national Pinch Point Programme, after the Enterprise M3 Local Enterprise Partnership, involving representatives from private and public sector organisations from north Hampshire and Surrey, submitted a bid for the cash.

Basingstoke and Deane Borough Council has put £500,000 towards the improvements and £874,000 is coming from Hampshire County Council.

The scheme is seen as a key part of plans by the borough council for the town to be seen as a leading business centre in the South East, and would complement its regeneration project at Basing View, which includes a new John Lewis at home and Waitrose store.

A Highways Agency spokesman said: "We are working with Hampshire County Council to reduce congestion on this busy roundabout, and to provide road users with reliable journeys.

“The design has been revised to improve traffic flows for southbound traffic, based on results from our detailed traffic modelling.”

So why are they clearing all the plants now? Couldn't they wait until the birds had finished nesting?

By the looks of some of the proposed lane markings, the proposal does not add anything like as much capacity at it makes out. North of the roundabout, the heaviest traffic flow at peak currently has two lanes going north. After the work is done, it will still have two lanes going north!

All this plan seems to do is allow more opportunity for the "too important to queue" brigade to queue jump and, guess what, contribute to congestion!

Can't see how this will help traffic southbound on 339 heading to M3 which has long queues morning and evening. Starting to look like this will cause months of delays for many of us with no benefit at the end of it.

"Basingstoke’s first so-called hamburger roundabout" - except the "old reading roundabout" over the ringroad in Oakridge was that style in the 70's, with traffic from chineham/popley being able to go through the roundabout and down Norn Hill

Only a flyover would relieve that problem. The moment traffic has to be stopped by lights, you get congestion.

Too often the argument is, "oh but that only happens in the peak rush" but the problem is that the situation will not improve as the population grows. We have become too scared of building roads, for the wrong reasons.

In as much as I can make out from the small diagram on the Gazette website.
I agree with 2 contributors. Why clear the trees while the birds are nesting. Only a small issue - unless you are a bird......
The main thing is that it should be a flyover, not just an updated set of traffic lights. There will be more traffic lghts than at present as far as I can see from the small diagram. Oh well, the road builders will make a shed load of money.
