Description: Lively, proud film by the Cement and Concrete Association looking at the construction of Hammersmith flyover. Has terrific scenes of road traffic from the 1930s and 1960s, and Hammersmith Broadway before the flyover. The film contains some fairly dense technical information, but also numerous great moments showing the flyover slowly rising over Hammersmith and indicating how challenges were met. Note also the interesting attitude to health and safety.
