On Feb. 2, more than 100 people gathered at the south entrance to the new 99 tunnel for the opening ceremony.
Commuters opened the three-day festivities with an 8K race that took participants through the new four-lane tunnel and over the Alaskan Way Viaduct.
The celebration marked the end of three weeks of a commuting nightmare, after transportation officials closed the viaduct to realign the highway into the new tunnel.
