Book excerpt: The thirteen projects take as their subject a site of contested transportation infrastructure--the Sheridan Expressway. By proposing new typologies for this site, these studies seek to mediate the spaces in the city where local and regional meet. Referencing the introduction of the modern parkway into the Bronx, the grading of the Central Park transverse roads, and other works that have redefined the relationship between parks and roads, author Jonathan Solomon suggests a system by which large projects might again be built in American cities.
