Highline Bridge

Semper Dive & Marine was contracted to install driven pile foundations for a Replacement Railroad Bridge owned by the Massachusetts Bay Transportation Authority located in Somerville, MA. The need for the bridge to be placed on a Driven Pile Foundation was due to the underlying soft compressive soils at the bridge location. The Structure is now fully supported down to Bedrock on an H-Pile Foundation. A
Outcome: Due to the existing bridge to be replaced and constrained on-site staging area, it was a challenging project. The crew was able to establish a safe and efficient working environment while conducting operations directly between live Railroad tracks. Strong and effective communication between RR Workers and the Pile Driving Crew allowed Semper to complete the work within the foul zone of the tracks with 0 incidents.
