Well done Sam. Realistically we can't solve all of the world's problems with this bridge but if we are targeted about our design and environmental goals (including human needs) this project could really put Portland on the map with an intelligent agenda. It's time for Portland to lead the rest of the world for once.

For those knee jerk isolationists, Portland is not an island where people go to avoid the world's problems.

P.S. Sam lives in the real world and nearby the I-5 crossing, as do I.
