These are the two ferries on the Two Ferry ride, run by Cycling Concepts in Rocky Hill. The NBW also has an annual ride out there, the Norwich Metric. Other organized rides use the ferries too I believe.
Hard to imagine Connecticut would shut down such wonderful links when the yearly cost is less than $400,000 for one bridge and a quarter million for the other. Maybe the local bike club should organize a ride to help cover the legal fees. You could operate both bridges for a year on the money an event like the 5 Boro Bike tour makes in registration fees.
