RIO VISTA — Rio Vista wants to see an improved intersection at Highway 12 and Church Road and the Solano Transportation Authority will help out with an initial step.
The Solano Transportation Authority will manage the state-required environmental study and engineering report needed before the project can move forward. The $600,000 cost is to be paid by traffic impact fees.
Doing this work gets the project ready for future design and construction, Solano Transportation Authority Executive Director Daryl Halls said.
The Highway 12/Church Road intersection is within Rio Vista along a narrow, two-lane section of Highway 12 just east of the Trilogy subdivision. Amerada Road also intersects Highway 12 almost at the same point, offset by about 75 feet from Church Road.
Church Road is a secondary access road to Trilogy. Amerada Road leads to an oil and gas company. But the importance of the intersection will grow if Rio Vista growth plans for new subdivisions in the area come to fruition.
In June 2010, the state Department of Transportation released a brief report on improving the intersection at a cost of $5.8 million to $7.1 million, depending on various project alternatives.
Caltrans wants to add left turn lanes, acceleration and deceleration lanes and eliminate the offset between Church Road and Amerada Road. No traffic signal is included, at least initially, the report said.
The report describes these steps as “short-term improvements” for the intersection. The long-term improvement envisioned for this section of Highway 12 is widening the highway to four lanes. But the Caltrans study doesn’t foresee this happening for years, perhaps not before 2025.
Improving the intersection may affect sensitive biological resources, the report said. An environmental study must do such things as survey the area for burrowing owls and Swainson’s hawks, it said.
