I’ve discovered few similarities between the city of Rotterdam, where I’ve been living for seven weeks, and Chicago. The most striking similarity is the nearly identical layout of the boulevard streets. While biking from my apartment in Rotterdam towards the cool neighborhood of Witte de With, I realized that as I was cycling on the side road of a wide street, I was really biking on a facsimile of Kedzie Boulevard in Chicago.
In the middle was a two-way “main drive,” where through traffic and buses ran, and on both sides, separated by a landscaped area, were one-way service drives for access to individual houses or apartment buildings – just like in Chicago. Other Chicago streets with this layout include Franklin Boulevard and Ogden Avenue.
The difference was that the city of Rotterdam implemented “filtered permeability,” by preventing motorists from driving more than one block at a time on the service drives. As a motorist driving on the service drive approaches the next intersection, there’s an “exit ramp” that carries vehicles over the landscaped area and onto the main drive.
Side streets that intersect the boulevard can only be entered from the main drive, eliminating the possibility of using the service drive to get around a backed up intersection on the main drive in order to turn right.
A bike path connects the “end” of this service drive to the start of the next one, on the other side of the intersection. Of course, the sidewalks are continuous. Doing a similar layout in Chicago would require eliminating only about one car parking space per block.
