King county has been awarded a $140M grant from the feds to experiement with tolling on SR-520. . We noted in June that the project was a semi-finalist.

The county plan calls for electronic tolling technology and express lanes on the new 520 bridge, which is undergoing mediation to help determine a final design. The electronic tolling would be similar to what is being used on the newly reopened Tacoma Narrows Bridge, state transportation officials say.

The money will help build transit across the 520 corridor — $41 million for an estimated 45 more buses — and $1 million will go to improving passenger-only ferry service for Vashon Island, King County Executive Ron Sims said.

New York City’s congestion pricing proposal is also getting money.
