If they ever put a speed cam on the I74 bridge in the Quad Cities they will get rich.  The limit is 50 going across the old, not too wide bridge and every time we travel across it there are people weaving in and out of traffic (traffic already over the limit).  Some people cross there at 70 and while I don't care how fast you drive out on the Interstate or other highways I don't like it on the bridge.

And it's especially not safe when weaving in and out.
