100 miles of street has a replacement value of approximately $42,000,000.
100 miles * 5280 ft/mile x 36ft ~ 19,000,000ft2
19,000,000ft2 * 1 yd2 / 9ft2 ~ 2,100,000 yd2
Average replacement value per yd2 ~ $20.00
$20.00 / yd2 * 2,000,000 yd2 = $42,000,000
Good planning and preventative maintenance saves $$$.
