Hertfordshire County Council provide an interactive map on their website showing upcoming roadworks across the area. You can access the map here or by clicking on the map image to the right.
When you first load the map it is likely to be showing a different area to Chorleywood. You can zoom in and out, and there is a search facility where you can specify a location – e.g. Chorleywood – and also over what period in the future you want to search. Click on the symbols on the map to see details of the works planned.
