Alma Road in Birkdale is closed due to gas work repairs. That is to say that the Upper Aughton end is completely barricaded off while at the Birkdale village end there is a notice at the side of the road to say the road is closed - but there is no notice to say "For Access Only".
Consequently, drivers who have not seen the side notice at the village end - drive all the way down Alma Road, to find the barricades right across the road, so they then use the extended road.
