"Among the many important highway construction projects undertaken in Missouri, the Express Highway through the City of St. Louis ranks among the first both because of the coast and difficulties involved, and because of the improvement in traffic conditions which it provided. This highway enters the city at the southwest corner of Forest Park, which is the junction of Skinker Road and Oakland Avenue. The accompanying map will give an idea of the location of the highway from this point to its end, a distance of approximately two and ninety-six one hundredths miles. The most noteworthy feature is that there are no grade crossings and traffic is permitted to enter and leave the Express Highway only at the "clover-leaf" intersections at Hampton Avenue and Jefferson Drive. There have been several unusual features incorporated in the design of this project; such as pedestrian overhead structures at Tamm Avenue, opposite the Arena, and opposite the Central Deaf Institute. Two pedestrian underpasses have been provided, one opposite Forest Park Highlands, which is an amusement company, and the other opposite the Forest Park Mounted Police Station; an equestrian underpass has been provided at Mackland Avenue to permit all horses with riders to pass under the highway. The writer supervised the inspection of the materials and much of the actual construction of the structures, the pavement, and the retaining walls" – Introduction, p. 1-2.
