Proponents of navigation expansion have long maintained that the only way to eliminate traffic delays on the Mississippi River is to expand the locks, a project that would cost over two billion dollars, take decades to complete and do little to benefit small farmers, rural communities or the environment. On the contrary, a number of small-scale, non-structural measures exist that would increase navigation efficiency immediately, cost much less to implement and better benefit everyone involved. This fact sheet explores these non-structural measures.
