About this tour

Seattle’s dramatic hills, waterways, and seismic setting have demanded ingenious solutions. On this private four-hour Seattle Engineering and Infrastructure Tour, connect the city’s landmarks with the challenges they were built to solve. Travel by private, air-conditioned vehicle as you explore major projects including the I-90 floating bridge, the SR-99 tunnel, the rebuilt waterfront seawall, and the Seattle Central Library. The route also takes in Fishermen’s Terminal, the Amazon Spheres, Gas Works Park, the Ballard Locks, and key neighborhood corridors. Along the Elliott Bay Trail, look for Boeing 737 fuselages moving along the rails. Rather than simply ticking off sights, your live English-speaking guide reveals how each structure and system helps Seattle function between saltwater and freshwater, on steep slopes and unstable ground. Private transportation, bottled water, and parking fees are included. See Seattle from an engineering perspective and discover the ideas beneath its familiar skyline on this Seattle Engineering and Infrastructure Tour.

How this score is calculated

This tour has no TourTruth score yet: Viator doesn't show a usable rating for it. It gets a score as soon as a provider lists one.

How the score works
  • Each provider rating is turned into a percentile: the share of that provider's ratings it beats, weighted by review counts.
  • Listings on different providers are combined in proportion to their review counts.
  • Tours with few reviews are pulled toward the average until more reviews come in, so a handful of perfect reviews can't top the list.
  • The result is shown from 0 to 10. Tours without a usable provider rating are not scored.
