Overpass rigidity?

We built an overpass from steel pipe rather than PVC, but as a result, took some liberties in assembling it so as to avoid a crazy number of beveled cuts and welding. The finished product is a bit, uh, bouncy. We've gone as far as inserting a second steel pipe that sits inside those called out by FIRST to add strength to the midspan joint.

Has anyone else with a field built to spec. found this to be true? I'm curious how much of the deflection we're seeing might be present in the FIRST fields or if it's something that's unique to ours that we should try to fix.
