Simulations

(Note: WMV files require Windows Media Player.)

SR 99 tunnel south portal and South Holgate to South King Street construction (February 2012) - Interactive simulation describes how the tunnel's south portal and the south end viaduct replacement will be constructed.

SR 99 tunnel north portal and Mercer Corridor construction (October 2011) - Interactive simulation describes how the tunnel's north portal and the City's two-way Mercer Street project will be constructed.

SR 99 construction bypass drive-through (August 2011) shows how SR 99 operates after October 2011, when the viaduct's south end was demolished. View on YouTube.

Tunnel drive-through video (October 2010) shows an early design concept for the SR 99 tunnel and the access provided at its north and south portals. View on YouTube or download WMV file.

Tunnel underground video (March 2010) shows the SR 99 tunnel’s route beneath downtown Seattle and its proximity to other underground structures. View on YouTube or download WMV file.

Simulated collapse of Alaskan Way seawall and viaduct (October 2009) shows what could happen to both structures if a strong earthquake were to shake the Puget Sound region. View on YouTube or download WMV file.

Tunnel boring machine animation (September 2009) explains how a bored tunnel is constructed. View on YouTube or download WMV file.

Waterfront video (July 2009) shows an early concept for the new Alaskan Way street. View on YouTube or download WMV file.

Looking southeast over old downtown Seattle, a snow-covered Mount Rainier looming in the distance.
Seneca Street off-ramp from Alaskan Way Viaduct under construction, 1961. Photo courtesy of the Museum of History and Industry. The south opening of the Battery Street Tunnel and the north end of the Alaskan Way Viaduct. The viaduct serves Seattle's downtown and surrounding neighborhoods and industrial centers. A view of the viaduct and downtown Seattle from the Bell Street Marina. A recent photo of the viaduct from Alaskan Way and the Colman Ferry Terminal.
The Port of Seattle relies heavily on the SR 99 corridor. The upper deck of the Alaskan Way Viaduct in the Pioneer Square vicinity. The south end of the Alaskan Way Viaduct. The viaduct is an important freight and commercial vehicle route. It connects the Duwamish industrial core to Ballard Interbay and North Seattle. Aerial view of present downtown Seattle and its two primary north-south highways, I-5 and SR 99. Time lapse view of downtown Seattle and distant Olympic Mountains.
The viaduct cutting through Seattle's central waterfront. The aging Seattle seawall, 2002. Microscopic image of L. Limnoria, commonly known as the Gribble. Gribbles have substantially contributed to the seawall's deterioration. Gribble damage to boards of a seawall platform. Looking north along the seawall.
Deteriorating Seattle seawall piers. Rotting boards from the seawall. Another view of the diminishing seawall. Damaged concrete support beams and exposed rebar after the 2001 Nisqually earthquake. Diagram of vulnerable points on the Alaskan Way Viaduct and seawall.
WSDOT crews repairing earthquake damage on the viaduct in April 2001. The Nisqually earthquake resulted in $3.5 million in repairs. Reinforced piers on the Alaskan Way Viaduct after the 6.8 Nisqually earthquake. Eroded concrete and exposed rebar on the viaduct's upper deck. WSDOT crews fix these wear and tear damages during earthquake inspections ever six months. Reinforced columns on the viaduct. Crews installing column supports to the most vulnerable area of the viaduct - across from Colman Ferry Terminal.
