You are offerding on a set lionel O scaleExtension bridge with rock piers used and there is no box and the train track does not come with the bridge. This came from a private collection. The bridgewas made in 1976 to 1987. Nice Features are realistic cut stone detailing, metal bridge bottom and theit is 3 3/4\"wide x 7\" high, 24\" long, this bridge is for \"O\" and \"O27\" gauge layouts. The rock piers are 4 3/4\" highand that makes the hole bridge 12\" high. The extension bridge is in good condition and would be a great addition to any train layout.
