Maryland Department of Transportation—Metro Interlockings Reconstruction

MDOT performed critical reconstruction work at three major Baltimore Metro interlockings during a partial metro shutdown from July 23-Aug. 12, 2016. The work was done to bring the track, track bed, signaling and power components to a State of Good Repair, which resulted in increased safety and reliability for system users. To complete the project on schedule and minimize the partial shutdown for users, MDOT developed and executed precise plans to procure long lead-time materials and stage construction during the outage. A wide-ranging public information campaign was enacted and shuttle buses were used between closed stations to assist users. The $17.1 million project was completed on schedule, minimizing inconvenience to users while making the system safer for them.Metro Interlockings Reconstruction Project--Maryland DOT
