Why we did it

The junction joining the A483 and A489 and the main route through Newtown was regularly congested. The industrial, commercial, leisure and tourist development of Newtown was hampered by congestion issues. Provision of this new bypass should help Newtown develop as a reqional centre in mid Wales.

Current progress

The bypass opened in early 2019. The project is now in its 5 year aftercare period. During this time, the Welsh Government are continuing to carry out any outstanding works and monitor the landscaping of the scheme. This will be completed in early 2024. 

How we consulted

We held a public consultation exhibition in summer 2009 in Newtown.

Proposals discussed the 2010 preferred route plus alternative options and were displayed at a public information exhibition in summer 2013. This resulted in a modified preferred route being announced in spring 2014. The route was viewed by over 600 people at another public information exhibition in spring 2014.

In summer 2015 there was a public local inquiry.
