Motorists are reminded that an overnight closure of the A47 at Postwick on Thursday night, 15 October, will herald changes to temporary traffic flows as the major improvement of the Postwick junction moves into its final phases.
The Thursday night closure of the A47 is to allow traffic to be switched from the old slip road, taking eastbound traffic off the A47, to a newly-constructed slip road.
This change is necessary for the safety of traffic on the A47.
The old slip road is too short, and is being closed and replaced because it cannot be extended. With significant housing and business park development already planned for the area, therewould have beena significant andgrowing risk of traffic queuing back down the slip road on to the 70mph dual carriageway.
The other major change on Thursday night is the closure of the original bridge over the A47 for essential maintenance and upgrading. Traffic will instead use the new bridge for the first time.
These temporary arrangements, which will be for around five weeks, will put pressure on the new access roads and junctions.Temporary traffic lights will be used at the Broadland Way/Peachman Way roundabout.
The changes will be made overnight on Thursday and will come into effect on Friday 16 October. An overnight A47 closure (8pm to no later than 6am)will be necessary. Westbound traffic will have a short diversion up and down the junction slip roads, but for eastbound traffic the A47 will be closed at Trowse, with traffic diverted via the A146, A143 and A12, returning to the A47 at Vauxhall roundabout, Great Yarmouth.
There will be a further closure of the A47 on Friday night (8pm to no later than 6am), when traffic from both directions will be diverted via the junction slip roads.
Norfolk County Council apologises for the delays and inconvenience caused by these closures and the temporary traffic arrangements. Work on the junction remains on course for completion before Christmas.
Further information is available on Norfolk County Council’s website (www.norfolk.gov.uk), including traffic flow plans and a more detailed explanation of the scheme and the reasons for the junction layout.
