MTA-NYCT Rehabilitation of the Culver Line Viaduct
- Client: MTA, New York City Transit
- Project Value: $178,800,000
The Culver Line viaduct, located between the portal of Carroll St. Station and the portal south of the Fourth Avenue Station, is a four-track system inclusive of two stations. The 90+ foot-high viaduct spans the Gowanus Canal and various streets in Brooklyn.
System integration was a key component of the Culver Line rehabilitation project. One of the first major challenges was the signal system. To advance the project from the first phase into the second phase, Judlau was required to move the train from its normal track to a newly constructed track that was installed during the first phase. This new track needed to be put in service with the existing signal control system due to the long lead time of the relay room equipment required for the new signal control system. TC Electric along with Judlau designed a plan and schedule for the signal. To accomplish the work under the project specific constraints, Judlau preserved the existing signal cases and logic that were on the original track and moved the cables over to the new track with new wayside signals, stops and insulated joints installed on the new track in conjunction with the new equipment that was not scheduled to be put in service until the final phase of the project.
Additionally, the installation of conduits at the 4th avenue station required the coordination with New York’s State Historic Preservation Office (SHPO). Through active dialogue and successful coordination, this work was completed within the required constraints of the owner and SHPO.
