SAN FRANCISCO, CA – Today, the San Francisco County Transportation Authority (SFCTA), together with the California Department of Transportation (Caltrans), the Treasure Island Development Authority (TIDA), and the Federal Highway Administration, commenced construction on the I-80/Yerba Buena Island (YBI) Westbound Ramps Improvement Project. The first of two components to the larger YBI Interchange project, the Westbound Ramps Improvement Project will improve traffic mobility and safety in the area.

“The SFCTA has placed the highest priority on inter-agency partnerships in order to ensure that our projects are delivered in a timely fashion,” said SFCTA Board Chair John Avalos. “We are pleased that this project has closely coordinated with several entities and is on track to meet our scheduled completion of mid-2016.”

The Transportation Authority is coordinating closely with Caltrans and TIDA to deliver the project, which represents the first major infrastructure improvement for TIDA’s planned redevelopment of Treasure and Yerba Buena Islands.

The YBI Westbound Ramps Improvement Project is being funded by a robust package of federal, state, and local TIDA funds. “This $49 million project received nearly $9 million from Proposition 1B, a 2006 voter-approved transportation bond,” stated Caltrans Director Malcolm Dougherty. “To date, more than $17 billion in Proposition 1B funds have been put to work statewide for transportation purposes.”

TIDA’s planned redevelopment of Treasure and Yerba Buena Islands calls for the development of 8,000 new homes – at least 25% of which are to be below market rate – as well as a K-8 school, several hundred thousand square feet of retail and office space, and a 275-acre park, among other new facilities. The redevelopment of the Island will eventually house approximately 20,000 new residents.

“The Yerba Buena Ramps Project will create a safer connection between the Islands and their neighbors in San Francisco,” said SFCTA Commissioner Jane Kim. “As the Supervisor for Treasure Island, I am excited to see the completion of the project, which will ensure safer circulation and enable the addition of much needed housing and jobs in the city.”

"The Yerba Buena Ramps Project is definitely our connection to the future,” added TIDA’s Board of Directors President Linda Fadeke Richardson. “It is an important milestone that will complement the years of community input we have integrated into the development of this important part of San Francisco."
