Please be advised that the developers will now be fully opening Black Dam roundabout in March 2016.
It was previously planned to phase opening of the ‘half hamburger’ arrangement in November 2015. This would have maintained two lanes on most of the approach roads to the roundabout.
However, a phased opening – rather than a delayed full opening – would require further changes to the traffic management layout later, as well as a significant number of off-peak lane closures in the New Year. Traffic signals would need to be on fixed timers initially and substantial numbers of temporary signs would be required. We consider this would be confusing and less safe for road users and the workforce alike.
With shorter daylight hours and the winter holiday season approaching, it was decided with their partners in Hampshire County Council and Basingstoke and Deane Borough Council that leaving the existing traffic management system in place was the preferred option. To minimise the impact of the works on the local economy over the Christmas and New Year period, work will be suspended between Wednesday 23 December and Monday 4 January.
The utility works are now substantially complete and within their control, thus allowing them to programme the end of the works without the need to factor in third party work. By delaying the opening of the carriageway through the roundabout, they will be able to complete construction of the new traffic lanes, install all signage, traffic signal equipment, new lighting and safety barriers. This will be safer and for all concerned and permit greater junction capacity at all times
Following the full opening of the junction, testing of the new equipment will take place, along with landscaping and minor remedial works.
