This bridge is now wider. Was 50mm but that was not wide enough for two lanes of vehicles or trains. now it is 70 mm wide. So price has gone up. 

I recently changed this listing from a 19 inch long to an 18 inch long so I am not limited to just one 3d printer to make this bridge. It takes days to make one and my largest 3d printer is only one that could make the 19 inch version. So i lowered to 18 inch so I can make on 4 large 3d printers. I also lowered price to reflect the difference. 

This is meant for a four Lane highway Bridge for cars. But can also be used for railway. It's a bigger Bridge compared to may 1 lane Train Truss version. and the shorter 12 inch two lane version. Measurements were custom by an customers measurements needs. everything is customizable with measurement changes. . Also added are two 18 inch Bridge fence rails that can be glued on yourself, or added yourself. This has to lay flat on heated bed plate when being made on 3D printer, so the rail fence cant be printed on the main bridge as is. Its 460mm long, 140mm tall, 70mm wide. again change scan be made some, as long as its not longer as this is made on my largest 3d printer and it can only be made up to 19 inches long. its a long complicated print. Over 3 days of 3d printing just to make one and these are made per order so If you order one depending on if there are any other orders be made in front of your order on my large 3d printer, it will take at least 4 days to ship out from time of purchase. cost is 74.99 plus shipping. 

This is a 3D printed Truss Bridge, that us designed for HO scale 1:87 for four lane Lane Train or two lane Vehicle Bridge. or can be used for your custom needs. Made by Spencer-3D.  Its a very tedious process to 3D print and takes several hours to make. this four Lane Arch Bridge takes over 3 days just to make one. I can make custom parts or pieces as well. I make a lot of different stuff and I have recently got into making ho scale parts. I can make other types of Bridges, or I can make custom ho scale parts. Let me know. Fast shipping If ordered inside United States. I  have 13 3D printers but only one is large enough to make this item, So it takes time to make. 

Length 460mm

Height  140mm

Width 70mm

Colors as is are silver and black top. I can make in other colors as well, or if want all in one color, I can do that as well. Everything is customizable.
