The first part of a voter-approved transportation bond will bring $25 million worth of freeway work to Tracy.

The San Joaquin Council of Governments applied for $300 million from the $19.9 billion bond passed as Proposition 1B, approved by voters in November 2006. On Wednesday, the California Transportation Commission endorsed nearly $1.8 billion for projects in the northern part of the state.

Included in that sum is $25 million to meet a COG request to add auxiliary lanes to Interstate 205.

It is more than half the $45.5 million needed to add extra lanes on I-205 that will connect on-ramps and off-ramps between Tracy Boulevard and Grant Line Road, and between 11th Street and Mountain House Parkway.

The new right-hand lanes will be added on both sides of the freeway for a total of 4.9 miles of new pavement. That project is slated to for 2010.

Many COG requests for funding, however, were turned down.

San Joaquin County didn’t get the $225 million it wanted for carpool lanes on Interstate 5 in northern Stockton that would be built in 2010. A request for $50 million for widening Highway 99 in southern Stockton was also turned down.

Transportation commission staff said that the I-5 widening should be reconsidered next year, and the Highway 99 widening money could come from a different bond.

Despite the cold shoulder for San Joaquin County, a major highway over the hill was slated for improvements. Tracy commuters should benefit from the nearly $174 million that was approved for carpool lanes to be added to Interstate 580 on the west side of the Altamont Pass.

The commission endorsed $101.7 million for a new lane for westbound I-580 between Greenville Road in Livermore to Foothill Road in Dublin. It also will set aside $72 million for a westbound carpool lane between Hacienda Drive and Greenville Road.
