Milestone considered the highways and transport implications of Lynefield Park, the redevelopment of the former Alcan smelting complex in Lynemouth, Northumberland.
A Transport Assessment and Framework Travel Plan were produced for the site along with the general arrangement of the two upgraded site accesses. A separate planning application was also made for the engineering works required to fill-in the void where the aluminium smelter once stood. From a transport perspective, this required a Route Management Plan for the HGV trips necessary for the works, and a quantification of the number of trips that would be required, both of which MTP were able to deliver.
One of the key challenges with the project was justifying trip rates that were lower than those within the Northumberland Core Strategy, but more representative of the site. Following discussions with Northumberland County Council, trip rates were calculated using the businesses currently operating at Lynefield Park through on-site Automatic Traffic Counts (ATCs), which were found to be significantly lower than within the Core Strategy. This meant that the study area for junction modelling was reduced and there was no longer the need to assess and potentially propose mitigation for some large strategic junctions.
Once trip rates had been agreed, trip distribution was calculated using 2011 Census data and junction modelling for the site accesses and surrounding junctions was carried out within PICADY and ARCADY software. This project had a successful outcome with planning permission achieved in 2018 and MTP are continuing to work with the developer in bringing the site forward.
