Geospatial Holdings has announced that it has been awarded a contract to map a 12-inch high pressure gas line in support of the Alameda Corridor Transportation Authority (ACTA) SR-47 Expressway Project in Long Beach, California.

The project involves the utilization of Geospatial's Smart Probe Pipeline Mapping Technology to map approximately 2,600 lineal feet of existing high pressure gas pipeline installed over 90 feet in depth under a highly congested navigable waterway undergoing a major expansion.

It is necessary to accurately locate and map this line as the overall project requires pilings to be driven in the area of the pipeline.

Mark A. Smith, Geospatial's CEO stated, "This project is an ideal example of the importance and versatility of our Smart Probe Mapping Technologies. I am not aware of any alternative method to map this pipeline under these challenging conditions and depths."

Project Description/Overview
The Schuyler Heim Bridge Replacement and SR-47 Expressway Project is being advanced through a joint partnership between Caltrans and the Alameda Corridor Transportation Authority (ACTA).

The project proposes to replace the seismically deficient Schuyler Heim Bridge over Cerritos Channel and add a four-lane elevated roadway connection to Alameda Street that will bypass three signalized intersections and five at-grade railroad crossings. The Heim Bridge is an essential service link between Terminal Island and the mainland in Wilmington.

This project will provide an alternative route from Terminal Island, a major generator of port-related truck traffic, and provide direct access to local distribution centers and warehousing facilities in the South Bay area, as well as I-405 and SR-91, thereby relieving congestion on the Harbor and Long Beach freeways.

The Schuyler Heim Bridge Replacement and SR-47 project will enhance the efficient, secure movement of goods at the nation's largest port complex, as well as reduce congestion and improve mobility.
