The new $960 million, 500-kV Trans-Allegheny Interstate Line (TrAIL) runs approximately two hundred miles from Southwestern Pennsylvania to West Virginia to Northern Virginia. Approved by PJM Interconnection (PJM), the regional transmission organization that coordinates movement of wholesale electricity in 13 Mid-Atlantic states, TrAIL will meet the region’s electricity needs and reduce overloading of the current transmission system.
Kleinfelder’s innovative foundation design concepts and collaboration with other team members resulted in value-added, provided efficient foundation installation, and prevented potential construction delays and costly change issues. TrAIL was energized on May 19, 2011, almost two weeks ahead of schedule. Furthermore, our team safely completed more than 70,000 service hours on the project.
