Police action near the airport on Wednesday afternoon closed a short portion of the Guadalupe River trail. The notice from the city parks department said the closure began at the Green Island Bridge.

During trail work on the Guadalupe River Trail in San Jose last summer, several references were made to “Green Island” and to the “Green Island Bridge.” Nobody knew where this was until a sign was installed on the Green Island Bridge during this trail work.

This is the bridge connecting San Jose International Airport to the long term parking lot at the far north end of the airport.

So we now know where the bridge is.

But where’s the island? Was there once a “Green Island” before the local water district built levees to contain the Guadalupe River? Does anybody know?
