ACTA has a rich history of designing and building major transportation infrastructure. Descriptions of our extensive Completed Projects, as well as some Current Projects are provided.

The cities and ports of Long Beach and Los Angeles and surrounding communities long sought ways to improve port access to accommodate steadily increasing cargo volumes while minimizing the impact on residents and businesses. A major result of that effort is the Alameda Corridor built by the Alameda Corridor Transportation Authority (ACTA). The Alameda Corridor, the first consolidated rail link of its kind, was among the largest public infrastructure projects in the United Stated when constructed. Running parallel to Alameda Street along much of its route, the Completed Projects are a series of construction projects divided into three sections – north, mid-corridor and south. ACTA has been involved in other planning and construction initiatives and advanced additional Current Projects.
