This is the same just fixed somethin that was botherin me. lol I originally intended there to be upside down stair blocks on the ceiling of the actual bridge. which is what i fixed. if you would rather have the regular stone brick blocks then the other still has them.
Pretty much took my Simple Minecart Bridge and made it bulkier. Little longer, wider and taller. Safe travel with walls and roof. Also with enclosed departure and arrival buildings. Bridge as is, is 94 blolcks long 5 blocks wide and 14 blocks high. Remember the Advanced Minecart Bridge #1 and Simple Minecart Bridge #1 are interchangeable for those times you want your track enclosed and those you don't. (Slight hight adjustment may be required)
