To those who think about building the Columbia River Crossing with a height lower than the Interstate 205 bridge, consider:
In hindsight, a catastrophic mistake was made in not providing fish ladders at Grand Coulee Dam. The result was that salmon spawning upstream from Grand Coulee were extinguished, along with their spawning grounds.
In hindsight, a disastrous mistake was made in not providing a navigation lock at Grand Coulee Dam. The result was that there is no inexpensive water transportation for industrial and agricultural products upstream from Grand Coulee Dam.
The same type of colossal mistake will repeat itself with a CRC bridge height lower than the I-205 bridge. A lower bridge height will forever close the Columbia River at Vancouver to producers’ and shippers’ products of a height greater than the I-205 bridge.
