The California Transportation Commission (CTC) has approved $487m for 82 construction projects to enhance transportation, safety and mobility in several districts across the state.

Of the total funds, $169m has been financed through Proposition 1B, a 2006 transportation bond approved by voters, while the remaining $318m has been provided by various state and federal transportation accounts.

To date, $16bn in Proposition 1B funds have been distributed across the state of California.

California Department of Transportation (Caltrans) director Malcolm Dougherty said: "California is investing in transportation infrastructure to support regional job growth and improve the state’s mobility for years to come."

In Los Angeles, the state has approved $38.1m for transportation projects on the San Diego Freeway, the I-10 between I-605 and the Orange Freeway, and to widen the Santa Ana Freeway (I-5) corridor.

"To date, $16bn in Proposition 1B funds have been distributed across the state of California."

CTC has allocated $1.39m and $676,000 for road widening projects in Fresno and San Diego, respectively.

In Marysville, the department will invest $29.85m for transportation projects in Placer County and El Dorado County, while in Irvine, the state has allocated $44.3m for projects in the cities of Placentia, Orange and Anaheim.

CTC has approved $48.9m in Oakland for transportation programmes in Solano County and Sebastopol.

In Stockton, Redding and San Luis Obispo, the state will invest $1.17m, $31.6m and $18m, respectively, to upgrade transportation infrastructure.

California Transportation Agency Secretary Brian Kelly said that CTC is taking steps to improve transportation, safety and mobility from Del Norte to San Diego County.

"These construction projects put people to work and improve the quality of life for millions of Californians," Kelly added.
