#63282: Million Dollar Mile Section of the Upper Grand Coulee

In order to build SR 155 in the 1940s along Banks Lake a large cut had to be made through the basalt cliffs. At the time it cost a million dollars to create this mile-long stretch of highway - an astronomical amount of money at the time. It is fun to imagine how the highway would be built in today's world and how much more it would cost.
