Chesapeake Bay Bridge-Tunnel TOC

Status: Existing

Description: The Chesapeake Bay Bridge–Tunnel (CBBT) TOC represents two operations centers (one on North and the other on the south). These operations centers are the failover systems meaning one can take over the other in case of the other one's failure. These systems currently collect wind and roadway data from bridges comprising the facility. The CBBT TOC shares incident information with VDOT and communicates with Virginia Beach's EMS for medical assistance during incidents. Additionally, CBBT TOC relies on the Virginia State Police for incident response as back–up to its own police and fire crews.

Stakeholder: Chesapeake Bay Bridge and Tunnel Commission
