The Galt community now has three choices for a new interchange at Highway 99's Central Galt exit to reduce traffic to the business area.
At a meeting that drew fewer than 20 people Tuesday, the City Council narrowed the six options in half.
Two of the options feature separate bridges across C and A streets, while a third option would have only a single, but wider bridge from Boessow Road to C Street.
While the City Council approved three interchange options, council members indicated one in particular they like best - known as option 13A - which would include separate crossings at C and A streets and four new stop lights as the freeway offramps in each direction meets with C and A streets.
The overpass won't be constructed for at least five years because money isn't available to build it, said Galt Mayor Darryl Clare.
Projecting Galt's eventual growth to a population of about 30,000, the Central Galt interchange would have 36,000 crossings per day, which would require six lanes if only one overpass is built, said Martin Inouye, a principal at Omni-Means, a traffic engineering consulting firm hired by the city.
With two crossings built, an estimated 17,000 vehicles would cross C Street, while 19,000 vehicles would cross A Street, Inouye said.
There are many pros and cons to each option, said Ron Boyle, Omni-Means' project manager.
For example, on the two options that feature double overcrossings, vehicles would no longer have access to the rear entrance of Galt Plaza on A Street. And southbound traffic on Camellia Way - where Estrellita Continuation High School and the rear entrance to Galt High School are located - would not be allowed to turn east on A Street.
Omni-Means will take about a year to develop cost estimates and environmental studies, Boyle said. When the studies are completed, Boyle said he will present a top choice for the council to consider.
That choice will be based on traffic movement, environment, right-of-way acquisition, ability to construct, design standards and cost.
One option, known as 2A, would cause Pine Street to become nearly a dead-end street, preventing westbound traffic on C Street from going to McDonald's or the Express Lane Chevron station and convenience store.
"Blocking off Pine Street, in any scenario, would be devastating to business," said McDonald's owner Charlie Golding. "If Pine Street were blocked off, I know we wouldn't be where we're at today."
Clare asked the Omni-Means staff to study ways for Pine Street businesses to have access to customers from C Street.
Option 2A would also include extending Civic Drive through Galt Plaza shopping center from C to A street and for Chabolla Avenue to be extended through Valley Oaks Shopping Center to connect Caroline Avenue with A Street.
