Case 4: Biddles Corner - AT600 Express Tolling
In 1996, the Delaware Department of Toll Roads was looking for a classification system which could function at a high level of accuracy in high speed express ETC lanes.
The first site was Biddles Corner, north of Dover on the SR1 (State Road 1) toll road. SR1 extends the length of Delaware and DelDoT needed to expand the capacity of the Biddles plaza to support the traffic growth. Increasing the number of lanes would have been difficult and expensive because of constrained right of way.
