Mr Ferguson announced in January that the route of the BRT system should not run across Prince Street Bridge or through the harbour for fear of clogging up the bridge and compromising the ambiance of the historic docks.
"This helps burst the bubble of those who have been claiming that my appetite for changes to the route around the harbour would mean the Department for Transport withdrawing all the money, " Mayor Ferguson said.
Mr Ferguson said a "number of potential improvements" would give a better connection on the route between Long Ashton and Temple Meads railway station.
