LEGO Bridge Version 18
This bridge was meant for a dual deck Rail bridge that could be pivoted up so we could access the inside of our display. The unit worked but I never modified the RR track to make it truly functional. Original show date GTE 2006.
This may not be totally LEGO legal, but hey it works. And even after all most a year of being built I could find no damage to my bricks. SO make these types of designs at your own risk, I take no responsibility if you stress your bricks too far and damage them.
