Sunbury Bicycle Users Group is urging the state government and Hume council to stop quibbling and extend a dangerous path beside Vineyard Road.
Group member Hector Bugeja said a short-term solution could be achieved as soon as someone put up the money.
Responding to a letter from Sunbury Labor MP Josh Bull that urged the council to work with VicRoads and Melton council to develop a joint approach for a link over the freeway, Hume chief executive Domenic Isola said the council stood ready to act once the government funded its share.
VicRoads has previously said path improvements would be considered as part of a $100 million program for new facilities across the state.
