Third bridge over the Mississippi at Memphis?

Tennessee officials say that a toll road may be the only possibility if motorists are insistent on a new bridge over the Mississippi at Memphis. Today's Memphis Commercial-Appeal quotes TDOT Commissioner Gerald Nicely as saying that such a bridge would take decades to construct unless tolls are used for at part of the financing. There are now two highway bridges over the river at Memphis, and state and local officials say a third one is badly needed. They cite the more than half-dozen bridges over the Mississippi at St. Louis as an example to show the need for more access across the river at Memphis-West Memphis. A new bridge is expected to cost up to $700 million.
