Chesapeake Bay Bridge Tunnel

Dear Chris:


I have been meaning to write to you concerning our use of the Plate Lock system at the

Chesapeake Bay Bridge Tunnel (CBBT) this past year. The CBBT is a 17-mile bridge and

tunnel span at the mouth of the Chesapeake Bay. It is a major north-south route handling

personal vehicle and heavy-duty truck traffic at 55 mile per hour speeds.


Our contract required the 8 roadway cuts @ the mouth of the two tunnels. The owner was very

involved in the plate hold down method. After several unsuccessful attempts using standard

steel roadway plates bolted directly to the roadway (18 wheel tractor-trailers hitting the plate @

55 mph on a 30ᴼ incline/decline) we contacted your company regarding the Plate Lock System.

The top two men in charge of maintenance at the CBBT (both ex-VDOT supervisors) agreed to

try the system.


We were all happy to say that the Plate Lock system worked without a hitch. Mr. Holloway of

CBBT indicated that if VDOT wanted a recommendation from him on the use of this system he

would be happy to give one. It is certainly our intention to use the Plate Lock system again in

the future and would highly recommend it.
