Los Angeles, CA – Today, the LA County Board of Supervisors voted to approve the South Whittier Community Bikeway Access Improvements project, which will bring a total of 8.4 miles of bike lanes as well as street improvements to unincorporated South Whittier, with sections adjoining the cities of Santa Fe Springs and La Mirada. The project will bring bike lanes to within one mile of the Metrolink’s Norwalk/Santa Fe Springs Station.
“We are not only adding bike lanes—we are repairing and expanding sidewalks for pedestrians, adding trees, and improving signage to make our community safer and more accessible for everyone. This project is a major investment in a better quality of life for South Whittier and its neighbors,” said Supervisor Hahn, whose district includes the area. “I’m proud that we’re now a big step closer to making this vision a reality.”

The South Whittier Community Bikeway Access Improvements project will install 4.6 miles of Class II bike lanes and 3.8 miles of Class III bike routes, without loss of travel lanes or parking. Additionally, the project will provide pavement resurfacing, installing wayfinding signage, construction of bulb-outs, reconstruction of curbs and gutters, sidewalks, and curb ramps, landscaping medians, removal and replanting of trees, replacing streetlights, and upgrading traffic signals with pedestrian push buttons with audio and vibration devices.
Work is expected to begin next July and be completed by January 2028, with an estimated total cost of $27 million. Funding sources include County road funds, Metro grants, as well as federal funds. Additionally, the City of La Mirada will contribute $67,000 and the City of Santa Fe Springs another $18,000.
