WMATA Cheverly Aerial Structure Jacking

Cheverly, MD

The Washington Metrorail system consists of a network of below grade tunnels, at grade rail, and elevated structures.  The aerial structure leading into Cheverly Station is supported on one end by an abutment that shifted over time.  In 2011, a rehabilitation effort was undertaken to return the bridge and rail to their original alignment and prevent further movement.

KEC worked with OTB Contracting and Clark Construction to design a method to lift the bridge and slide it into its original position.  KEC designed the temporary structures along with the jacking and sliding systems.
