M4 (Junction 34) to A48 Transport Improvements


 The Council has been working with an independent technical consultant to develop proposals for a new road linking the M4 and A48 and a new park and ride at Junction 34 of the M4. 


Two possible road routes were identified as part of a WelTAG Stage Two study, both of which would improve links between the M4 and A48, reduce journey times to the airport, and help tackle local traffic congestion.


The public and other interested groups were asked to comment on these proposals in 2018. The Review Group (who were appointed to make recommendations) considered the matter on 02 October 2018.


The Review Group and Council Cabinet took the decision to undertake further feasibility work looking at improvements to the existing road which was undertaken as a WelTAG Stage Two Plus study.


A consultation on the WelTAG Stage Two Plus was undertaken between 30 September and 23 December 2020 and was reported to Cabinet in March 2021.



This scheme is no longer being taken forward as it did not attract funding from Welsh Government beyond WelTAG Stage 2 plus.
