Does anyone have suggestions on how and with what to make vehicle roadways on an HO layout. I am looking to make two lane county roads and perhaps a small town street or two. I have read where a two lane HO scale roadway should measure 3.5 inches across. A small town street would be larger if there would be on street parking. I was thinking of piecing together Woodland Scenics foam road bed for vehicle roadways. Any suggestions and advice is greatly appreciated.
