Details of the scheme to improve junction 47 on the A1(M)

The A1(M) J47 and adjacent A168 and A59 junction lie in a rural setting. A1(M) J47 provides access from the strategic road network and to the towns of Knaresborough and Harrogate to the west and to the City of York to the east. The A168 runs parallel to the A1(M) between Walshford and Dishforth.

Scheme Background

Junction 47 of the A1(M) suffers from peak hour congestion when queuing occurs along both the northbound and southbound A1(M) exit slip roads. These queues can extend onto the A1(M) and represents a safety concern. Queueing fluctuates throughout the peak period resulting in unreliable journey times when using A1(M) Junction 47 and the adjacent A59 and A168 link road junction. This situation is amplified further during periods of higher demand such as those experienced during the Great Yorkshire Show, where congestion occurs across a large geographical area. Vehicles waiting to exit from the A168 Link Road at the A59 T-junction have been observed having difficulty due to both insufficient gaps between vehicles on the A59 and queues temporarily extending from Junction 47 through the T-junction with the A168.

Junction upgrade will support future growth

Work is scheduled to begin this month on a multi-million-pound project that will support the future growth of the Harrogate and Knaresborough areas.

Improvements will involve widening three of the four slip roads onto and off the roundabout to increase capacity. The other major upgrade will be the installation of traffic signals on the roundabout to improve the flow of traffic, addressing the issue of vehicles queuing down the slip road onto the A1.

In addition, nearby junctions will be improved. Traffic signals will be added to the T-junction between the A168 and the A59 a short distance from Junction 47 on the York side. This will benefit drivers turning on to the A59 and will improve safety.

The contractor is Farrans Construction and the scheme has been designed and will be supervised by Aecom.

Junction closures

Traffic Management planned from Monday night 25 January 2021 for 5 Nights and from Monday night 1 February 2021 for 5 nights;

  • A1(M) J47 southbound merge (on slip) slip road and northbound diverge (off slip) slip road night closure.
  • A59 reduced to one lane under 3-way lights.

Traffic Management planned from Monday night 8  February 2021 for 5 nights and from Monday night 15 February 2021 for 5 nights;

  • A1(M) J47 southbound diverge (off slip) and northbound merge (on slip) slip road night closure.
  • A59 reduced to one lane under 3-way lights.

The work would start each day at 8pm and will be removed by 6am subject to weather and traffic conditions.

Following completion of this work, the upgrading of the A59/A168 slip road will necessitate a full closure of the slip road. This could be in place for up to 16 weeks, but every effort will be made to minimise the duration of the work.
