Alaskan Way Viaduct and Seattle Waterfront Transformation: Comprehensive Visiting Guide

Date: 04/07/2025

Introduction

Seattle’s Alaskan Way Viaduct, once a prominent double-decker freeway framing the city’s waterfront, played a critical role in Seattle’s urban development for over sixty years. Originally constructed in response to mounting downtown traffic and completed between 1949 and 1966, the viaduct carried tens of thousands of vehicles daily and dramatically shaped the city’s relationship with Elliott Bay (HistoryLink, Seattle Times, WSDOT). However, its imposing structure also created a formidable barrier that limited access to the waterfront and stifled the area’s potential for public enjoyment and ecological health (Waterfront Seattle, KUOW).

After the Nisqually Earthquake in 2001 exposed the viaduct’s seismic vulnerabilities and ignited extensive public debate, Seattle embarked on a bold plan to replace the viaduct with the SR 99 deep-bore tunnel. The tunnel opened in 2019, and the subsequent demolition of the viaduct paved the way for a landmark waterfront revitalization project.

Today, the corridor is home to a 20-acre Waterfront Park, featuring pedestrian promenades, public art, green spaces, and the iconic Overlook Walk—a new grand pedestrian bridge offering panoramic views and direct connections between Pike Place Market and Elliott Bay (Waterfront Park Seattle, SDOT Blog). This guide provides an in-depth look at the site’s history, key visitor information, travel tips, and nearby attractions to help you make the most of your Seattle waterfront experience.

Historical Background: Viaduct Conception, Construction, and Urban Impact

The Alaskan Way Viaduct emerged from 1930s plans to address Seattle’s traffic congestion. Construction began in 1950, and the central span opened in 1953, with subsequent extensions completed by 1966 (HistoryLink, Seattle Times). The viaduct ran 2.2 miles along the waterfront, carrying U.S. Route 99 and later State Route 99, serving as a vital passage for up to 110,000 vehicles per day (WSDOT, Wikipedia).

Despite its utility, the viaduct’s design reflected mid-century priorities that favored cars over pedestrian access and environmental considerations (CNU). Its presence cast long shadows, physically separated downtown from the bay, and limited public engagement with the waterfront.


The Push for Replacement and Demolition

The 2001 Nisqually Earthquake dramatically highlighted the viaduct’s seismic risks, leading to a decade-long civic debate over its replacement. Through public votes and long negotiations, Seattle rejected both a new elevated highway and a shallow cut-and-cover tunnel. Ultimately, a deep-bore tunnel was chosen in 2009, funded with $2.8 billion in state money (Wikipedia).

The viaduct closed permanently in January 2019. Its demolition was a carefully orchestrated process, dismantling 1.4 miles of concrete structure without explosives to protect adjacent historic districts and active rail lines. Nearly all demolition materials were recycled (IBTTA).


The Waterfront Today: Features, Hours, and Accessibility

Overlook Walk

The Overlook Walk is the crown jewel of the new waterfront. Opened in October 2024, this elevated bridge and park connects Pike Place Market with the waterfront, bridging nearly 100 feet in elevation. Visitors enjoy 360-degree views of Elliott Bay, the Olympic Mountains, Mount Rainier, and the Seattle skyline.

Features:

  • Landscaped terraces with native plants
  • Family-friendly amenities (slide, climbing wall)
  • Accessible pathways and elevators
  • Ample seating and covered gathering spaces

Hours: 7 am – 10 pm daily (Waterfront Park Seattle).


Pier 62

Pier 62 is a revitalized community hub, reopened in 2020. It hosts free public events, outdoor markets, concerts, and wellness classes. The floating dock provides water access and scenic views.


Pioneer Square Habitat Beach

Opened in 2023, Pioneer Square Habitat Beach restores shoreline ecology, supports salmon passage, and offers peaceful bay access close to historic Pioneer Square.


Promenade and Historic Piers

The waterfront promenade is a pedestrian-friendly boulevard lined with shops, cafes, and public art. Railroad Way South features tree-lined paths and rotating Indigenous art installations.

Iconic piers continue to offer:

  • The Seattle Great Wheel for panoramic rides
  • Waterfront dining and shopping
  • Access to ferries, water taxis, and cruise terminals

Seattle Aquarium Ocean Pavilion

The Seattle Aquarium Ocean Pavilion opened in 2025, expanding the aquarium’s mission with immersive exhibits featuring sharks, rays, coral species, and more. Art by Dan Friday (Lummi Nation) honors Coast Salish stewardship.

Arts, Culture, and Community Programming

The waterfront features permanent and rotating public art, with a strong focus on Indigenous artists (Waterfront Park Seattle). Upcoming highlights include a sculptural playground at Pier 58 and the Cannonball Arts venue in partnership with the Muckleshoot Indian Tribe (Visit Seattle). Friends of Waterfront Park curate more than 270 free events annually, including concerts, dance, markets, and wellness activities (Waterfront Park Seattle).


Accessibility and Sustainability

Accessibility is a core part of the design, with elevators, sloped walkways, and seamless connections between Pike Place Market and the waterfront (SDOT Blog). Habitat restoration at beaches and along the shoreline supports native species, and landscaping uses drought-tolerant plants native to the region.
