taxi fare from gujo city to bus stop

Please advise how much is the taxi fare from gujo hachiman jokamachi plaza to gujo hachiman inter bus stop along the expressway. I understand I have to take a taxi to the bus stop near expressway (not convenient) to take a bus to takayama. Please advise an easier way to get to takayama.

Depending on where around Gujo you start from, it will probably cost around 800-1000 yen.

Please advise an easier way to get to takayama.

I just checked my notes - last April it cost me 1020 yen to go to the Highway Bus Stop from a taxi garage right on the other side of the river from the Plaza.
For your info, the bus stop is in the middle of nowhere - doesn't even have a vending machine.....;-) I don't mean that to say it's unsafe - just nothing to do while waiting if you're early.
