Backers of an Oregon plan to replace the Interstate 5 bridge across the Columbia River hope to get a special session of the state Legislature as soon as this month to pass a new plan to finance the project.

The Oregonian reports the new financing plan relies heavily on tolls, more than $1 billion worth.

The project has been in doubt since the Washington Legislature decided against putting up $450 million to match Oregon's contribution.

But proponents such as Democratic Rep. Tobias Read of Beaverton say the project is still needed. Gov. John Kitzhaber is a backer, as are business and labor groups.

It faces a variety of skeptics, including Washington state residents opposed to including light-rail trains as part of the project.
