Addition by Subtraction
We are taught in math classes that whenever you remove a negative, the net result is positive. When it comes to thinking about planning options, sometimes considering addition by subtraction opens up a whole new set of choices. The same idea can be applied to the I-70 depressed lanes separating the Arch grounds and riverfront from downtown St. Louis.
The image above is a computer generated perspective of the I-70 depressed lanes and Memorial Drive between the Arch grounds and the Adams Mark Hotel. The image shows that currently there are 12 traffic lanes between the Arch grounds and the Adams Mark.
If the depressed lanes were removed, there would be space for a 6-lane configuration of Memorial Drive, with valuable land reclaimed for redevelopment. With limited funding resources, developing the reclaimed space with a mix of commercial and residential uses would provide a source of revenue to help fund the capital cost of building the new Memorial Drive.
