Great Highway Would Need New Traffic Lights If Reopened to Cars, Costing $13.2 Million

Key Takeaways:

• The Great Highway has been closed to vehicles since 2024.
• Reopening the highway would require $13.2 million in traffic signal upgrades.
• Sunset Dunes Park, created in the same area, cost the city $700,000.
• SF politics and ballot measures could shape the future of the roadway.
• Funding decisions loom large for both transportation and recreation planning.

Background on the Closure

The Great Highway was shut down to vehicle traffic in 2024, a move that initially aimed to ease maintenance costs and give residents more pedestrian-friendly open space. In the years since, the debate has continued over whether reintroducing cars is worth the financial investment.

Assessing the $13.2 Million Question

City officials now estimate that replacing and modernizing the Great Highway’s aging traffic signals would require $13.2 million. This figure highlights the scale of investment needed to bring back vehicles to the thoroughfare. By contrast, installing Sunset Dunes Park cost a relatively modest $700,000. Some stakeholders argue the steep signal upgrade price could be better spent on other areas of city development.

Comparing Costs: Park vs. Roadway

The stark difference between $13.2 million for traffic lights and $700,000 for the new park underscores a broader debate over budget priorities. Proponents of a car-free future say the cost savings justify keeping the highway closed. Others, however, believe reopening to vehicles could address traffic overflow in surrounding neighborhoods.

Political and Public Considerations

San Francisco’s political landscape often involves ballot measures on infrastructure projects, and this scenario is no different. Elected officials and community leaders continue to weigh the merits of restoring vehicle access versus preserving a unique public space. As potential ballot initiatives loom, local voters may ultimately decide the direction of the Great Highway.

Looking Ahead

The question now is whether the city will commit the multimillion-dollar budget required for new traffic signals. With Sunset Dunes Park already in place, the tug-of-war between open space advocates and drivers is far from settled. As debates evolve, the outcome could shape future approaches to transportation planning and public land use across the city.
