Gwynedd’s improvement of a 10.2km single carriageway road running through Wales will significantly improve residents’ quality of life.
A487 Llanwnda to South of Llanllyfni Improvement
Improvement of 10.2km of single carriageway trunk road, with 10 structures and significant environmental constraints.
The new road bypasses the villages of Llanllyfni, Penygroes and Groeslon, reducing the volume of traffic and significantly improving the residents’ quality of life. A notable feature of the scheme is the quality and quantity of natural stone walling and “cloddiau”.
The scheme passes close to Glynllifon, site of a major lesser horseshoe bat roost. A variety of measures have been employed over the years in attempts to mitigate the effect of the scheme on the bat population, and work is still being carried out to monitor the effectiveness of these measures.
