17 Macquarie St., Sydney, Australia (1925)
Woodblock Paving Macquarie St., Sydney, Australia (1925) City pavements required some roughness so that horses could get a foothold and traction. Wood blocks were considered ideas (for a while) because they could mimic the foothold of cobblestone or block pavement, but the wood muffled the sound of the horseshoes. Problem was, wood deteriorated quickly (3 to 5 years for a plank pavement). Wood blocks treated with creosote to make them last upwards of 10 to 15 years (likely an exaggerated claim). Wood blocks lost popularity in the U.S. partly because of a couple of: Chicago Fire (1871). Streets with creosote soaked wood blocks served to spread the fire rather than serve as fire barriers. They didn’t last in may places, especially Washington, D.C. (1878) – lasted 5 years and city spent 20 years paying off bonds for a pavement that no longer existed. Introduction of asphalt pavements and concrete foundations. From the City of Sydney's Sydney Streets exhibition (www.cityofsydney.nsw.gov.au/history/SydneyStreets)

19 Woodblock Paving Overlaid with Hot Mix Asphalt
Park St., Sydney, Australia (1929) Many streets were overlaid with a thin layer of “sheet asphalt”. Concrete was often used as a base and then surfaced with asphalt. Concrete shattered under iron horseshoe loads but could withstand more loads without deforming. Solution was to pave concrete and then surface with softer, smoother asphalt. From the City of Sydney's Sydney Streets exhibition (www.cityofsydney.nsw.gov.au/history/SydneyStreets)

20 Independent Asphalt Paving Co.
Seattle (ca. 1907) Paying for Roads/Pavement Generally abutters paid for improvements. Originally they paid for roads and pavements independent of the City. Later, special assessments became common, although the only thing the City really did was provide engineering advice and coercive and borrowing power. Often, quality of pavement was bad as abutters sought cheapest fix. Parking was sometimes included between sidewalk and abutters. People were allowed to plant there but not build (still have vestiges of this today). Seattle Photograph Collection, UW Digital Collections
