SEATTLE (AP) — A state study suggests that even a modest toll would result in traffic diverting away from a tunnel on the Seattle waterfront onto city streets.

But the state could meet the $200 million it is contributing to the $3.2 billion replacement project for the aging, earthquake-vulnerable viaduct. The tolls would also pay for maintenance.

The state Department of Transportation study was presented Wednesday to a joint government committee studying how to raise the $200 million.

The early stages of replacing the Alaskan Way Viaduct with a tunnel have already begun with crews tearing down the southern section of the elevated highway.

The study looked at tolling ranges between 75 cents to $3.25. It says that “even modes mid-day tolls” lead to diversion between 30 and 50 percent of traffic.
