Digitised 1970s San Diego highway footage reveals lost era of commercial design
The Internet Archive hosts a collection of photologs originally recorded by the San Diego Transportation and Storm Water Department, highlighting the visual shift from manual craftsmanship to computer-aided precision.
High-resolution scans of 1970s highway photologs, originally captured by the San Diego Transportation and Storm Water Department, have been digitised and released online via the Internet Archive. The footage, sourced from 35mm film and depicting street life from 1973, offers a detailed look at the era’s distinct visual landscape, characterised by pastel-coloured vehicles and whimsical, non-standard signage.
The collection stands in sharp contrast to earlier archival releases, such as the low-resolution footage from Connecticut’s 1980s highway surveys. The collector described the San Diego scans as the crispest and most beautiful photologs seen, noting that colour correction and contrast boosting were required to remove a grey veil from the original unaltered videos. This enhancement reveals a vibrant world of family restaurants, gas stations, and commercial establishments that have largely vanished from the modern streetscape.
Visible businesses in the footage include Bonanza, Jack-in-the-Box, Fotomat, 76 gas stations, and Texaco. The economic context of the period is preserved in the pricing data, with low-lead Fire Chief fuel recorded at $0.34 per gallon. The imagery captures a time before the ubiquity of digital screens, showing pedestrians and drivers engaged with their physical surroundings, a scene that graphic designer Aaron Draplin has analysed in the context of broader design shifts.
Draplin, owner of Draplin Design Co, attributed the decline of such distinctive signage to the advent of computer-aided design tools. He noted that while modern designers often attempt to replicate the aesthetic, the precision of digital software removes the imperfections inherent in earlier manual methods. According to Draplin, these imperfections provided a unique character that filters and texture tricks cannot fully replicate, marking a significant departure from the manual craftsmanship of the mid-20th century.
The Federal Highway Administration’s Manual on Uniform Traffic Control Devices (MUTCD) now sets federal standards for traffic signs, creating a uniformity that contrasts with the eclectic and often motorised signage seen in the 1973 footage. The digitisation of these photologs, which date back to programs initiated in 1961, provides a tangible record of this transition, preserving the visual history of American infrastructure before the standardisation imposed by modern regulatory and digital frameworks.
