WSDOT released four total videos detailing routes to get drivers to southbound 99, northbound 99, south through Seattle, and north through Seattle.

In terms of major changes, one of the bigger ones the videos describe involves Harrison Street, which will cross over Aurora Ave North for the first time in 60 years.

Routes through the two-mile tunnel will begin on the north end near Seattle Center, and by the south end near the stadiums.

As you approach the Space Needle, you’ll have two choices: Stay on southbound 99 to enter the tunnel, or exit left to cross over Harrison to Denny Way and downtown.

Entering the tunnel from the south end on NB 99, you’ll have the choice to either bear left to enter the new tunnel, or exit to the right to a new intersection at South Dearborn Street, to get either downtown or onto Alaskan Way.

You can check out all four videos below.
