Central Business District Roads include those similar to Woodmont Avenue in Bethesda and Wayne Avenue in Silver Spring.

Main Road Maintenance

These roads are usually maintained by repaving. A new layer of asphalt (usually 1" to 2") is placed over the existing surface after underlying roadway repairs are made. When the layers build up in such a way as to inhibit drainage and/or driveway crossings, the layers are milled or ground off. This allows for a new surface to be placed. The milling process is also used where many underlyng roadway repairs leave the road in a rough condition.
