This is probably the best history I've read of the planning of I-94 between Minneapolis and St Paul, and also an excellent explanation for the state of politics in Minneapolis today, in that it indirectly recounts the birth of today's neighborhoods. I'd describe the writing as youthfully academic, which is fine in the first half of the book, which consists of four case studies of planning initiatives or controversies, but can be deadly in the second half, in which Altshuler waxes theoretical on the state of the planning art (or science, maybe - there is a section debating which camp planning falls into). The first half will be of interest to mid-twentieth century MSP history buffs, but the second will only interest the most diehard planning nerds.
