Bridge Magnets

If you know how I built my signature Rock River scene, the two lattice truss spans are held in place by four ceramic magnets for easy removal if necessary. The same approach will be used on the I-280 overpass. I need to have access to the eventual scenery under the bridge, and I discovered that the neodymium magnets I had on hand fit perfectly on top of the four main bridge shoes used on the piers. I’ll install some narrow tin on the underside of the bridge girders for the connection.
