A reinforced concrete road bridge, width 18 metres including footpaths, to match my 18 metre streets, crossroads and road junctions (which were made for TRS2004 and are compatible with later versions). Made originally for crossing a river and to be used in conjunction with 'DDD Bridge 18 end' (Kuid2:275817:60637:1) and 'DDD Bridge 18 support' (Kuid2:275817:60640:1). Not suitable for use as a rail bridge unless one with footpaths is needed.
