The viaduct won't be torn down for a couple of years, but that hasn't stopped officials from working on a tolling plan for the new tunnel.
After six different tolling models failed, lucky number seven could be just right.
In addition to generating money, the plan has to keep cars and trucks from avoiding the toll and jamming up traffic on Seattle side streets.
Maud Daudon with the Viaduct Replacement Advisory Committee said the group has to find that perfect balance of generating enough money while also enticing drivers to actually use the tunnel.
"I think we're getting closer and closer," she said.
The toll needs to rake in $200 million to help pay for the tunnel, as well as another $160 million for operations and maintenance, $85 million for insurance and $190 million for repairs.
"There's a lot of money generated through these tolls and you know, honestly, that should help a lot with the components of building and maintaining that tunnel," Daudons said.
Under the latest scenario, the toll would be $1 on weekdays and weekends, and $1.25 during peak times of 6-9 a.m. and 3-6 p.m.
Some people say they'd gladly pay the toll, but others aren't sold on the idea.
"I would definitely try to avoid it," one driver said.
All seven tolling scenarios will be sent to the state Transportation Commission, which will set the final toll.
