Treasure Island infrastructure project secures $4M funding and includes public art initiative

The San Francisco City Council meeting on July 9, 2025, highlighted significant advancements in the West Side Bridges project on Treasure Island, marking a major milestone in municipal infrastructure development. The project, which includes a new retaining wall designed to meet stringent seismic standards, aims to enhance traffic flow and safety in the area.

Key features of the project include an undercrossing that will facilitate traffic movement from San Francisco to Treasure Island, as well as a public art component being developed by artist Mosaic. The art plan has received approval from the art commission, and the artwork will be visible from various vantage points, including the Bay Bridge.

The meeting also addressed the joint trench work associated with the project, which will house essential utilities such as power and streetlight conduits. The estimated cost for this trench work is approximately $500,000, and it is crucial for ensuring that the infrastructure is adequately powered and serviced.

Two Memorandums of Understanding (MOUs) were discussed, detailing financial commitments and construction responsibilities. The city has pledged $3,505,000 towards the project, with the Transportation Authority (TA) securing the remaining funding through various grants. An amendment to the MOUs will increase the city's financial contribution to $4,050,000 and obligate the TA to obtain necessary city permits for the joint trench work.

Council members expressed gratitude for the federal funding support, particularly acknowledging former Speaker Nancy Pelosi's role in securing resources for the project. The meeting concluded with a positive outlook on the project's progress, which is reportedly on budget and on schedule, emphasizing the importance of infrastructure in supporting the community's needs on Treasure Island.
