A study that takes a look at Highway 12 improvements from an economic standpoint will be released 6 p.m. Thursday at a workshop in Rio Vista.
The Solano Economic Development Corporation and the Solano Transportation Authority conducted the study.

It is designed to evaluate the potential economic benefits and needs of the corridor from Lodi through Napa, and preliminary results were discussed at a breakfast meeting earlier this year.

The Rio Vista presentation will take place at the D.H. White Elementary School multipurpose room, 500 Elm Way.

Consultant Economist Robert Fountain of Benicia is expected to talk about the economic effects of widening Highway 12 to handle more cars and provide better efficiency.

The corridor in Solano County faces significant challenges, particularly in Rio Vista, where replacement of the Rio Vista Bridge has been identified as a big need.

The current study does not include Vallejo, though the city will see some impacts from Highway 12 improvements, planners have said.
