Work is underway on the final and most important phase of a project in eastern Los Angeles County that aims to relieve congestion in the worst truck bottleneck in California. Officials broke ground earlier this month on Phase III of the State Route 57/60 Confluence project in the cities of Diamond Bar and the City of Industry.
The project was originally slated to launch in 2025 but the LA Metro board of directors voted in January to accelerate funding of the $441 million project. The San Gabriel Valley Council of Governments (SGVCOG) awarded Skanska a $267-million contract in April to make the mainline freeway improvements, with completion scheduled for July 2028.
