Parkway revamp planned

Major schemes planned for key Peterborough road

The Cambridgeshire and Peterborough Combined Authority (CaPCA) has approved £1m to draw up plans for major improvements to Peterborough’s Nene Parkway.

Members of the combined authority’s transport and infrastructure committee have approved the funding to pay for a business plan which will outline improvements to the A1260 Nene Parkway near Serpentine Green where it meets Junction 3 of the A1139 Fletton Parkway, and at Junction 15 of the A47.

Mehmet Ahmed, CaPCA transport program manager, said: “Junction 3 of the A1139 where it meets the A1260 is a large, grade-separated junction between two of Peterborough’s busiest strategic roads.

“The junction is a crucial cornerstone of the parkway network, connecting the A1139 Fletton Parkway and A1260 Nene Parkway, thus providing the majority of access to south-west Peterborough.

“It is used for trips from across the Peterborough area, and experiences significant peak hour congestion on the A1260 Nene Parkway and the A1260 ‘The Serpentine’ approaches and is heavily used by trips in the southwest of Peterborough.

“A large number of facilities, businesses, and residences are also accessed by the southern arm. Because of its strategic location, the junction is critical to Peterborough’s growth aspirations.”

At the outline business case stage, the project would require improving slip roads and adding extra lanes andnew traffic signals.

Mr Ahmed added: “Junction 15 is a partially signalised grade separated roundabout (positioned beneath the A47 TrunkRoad),whichissituated on the western edge of Peterborough’s urban area.

“The junction provides access to the A1260 Nene Parkway, Bretton Way, Thorpe Wood and the A47 Soke Parkway and it too is heavily used by trips between the west of Peterborough and the city centre, and a significant proportion of north - south trips as it provides access to one of only three river crossings within Peterborough.

“The junction also provides direct access to a major employment centre (Thorpe Wood) and accommodates a large number of peak hour commuter trips.

“The outline business case has been completed and the developed scheme will provide the necessary increase in highway capacity to unlock congestion and significantly reduce delay at Junction 15, which is a major pinch-point on the network and this will improve the capacity and operational performance of the Peterborough parkway system which is crucial to supporting further growth.

“In addition, improvements at Junction 15 are expected to have wider network benefits beyond the parkway system, particularly to the A605 Oundle Road which experiences congestion as vehicles queue back from the northbound on slip onto the A1260 Nene Parkway (towards Junction 15) during the PM peak hour.”

The project is planning to alleviate the following issues: queueing on the A1260 Nene Parkway northbound approach to the junction in excess of one-mile affected Junction 32 in the PM peak period; queueing on the A47 eastbound off-slip that extends back onto the A47 affecting the mainline flow; and conflicts occurring between the dominant movements at the junction.

Mr Ahmed said the option being considered would include the folllowing; widening of A1260 Nene Parkway northbound to three lanes from Junction 33; three-lane circulatory on Junction 15 between the A1260 Nene Parkway approach and the Bretton Way exit; replacement of the pedestrian footbridge over the A1260 Nene Parkway (to facilitate the creation of a third northbound lane); Extension of the flare on the Thorpe Wood to Junction 15 by approximately 30 metres; zebra crossing over Thorpe Wood close to the existing bus stops; reconstruction of the footpath between Thorpe Road Bridge and Longthorpe.

Metro Mayor James Palmer said: “It’s very important that we all learn from what has happened in Peterborough because it is a superb example of what can be achieved if you put advanced infrastructure ahead of housing delivery, everything thereafter happens much more smoothly.

“I’m not saying necessarily that we should look to the car as the provider for our infrastructure incentive, as those who looked to develop new-towns like Peterborough did in the 1960s and 1970s, but we can do the same with CAM Metro as Peterborough has achieved with its forward thinking.

“Members have already mentioned that Peterborough is the third or fourth fastest growing city in England – but when it was formed the population was only about 30,000 and now exceeds 200,000 with that growth seemingly achievedmuchmoresmoothly than in other places.”
