We studied the effect of the distributed Josephson current of a large one-dimensional edge junction on macroscopic quantum tunneling. An explicit expression for the Lagrangian of the whole system was derived from which we obtained the reduced Euclidean action for the tunneling mode. The result can be used to calculate the quantum tunneling rates in various cases. The measurement of quantum tunneling in such a system was also discussed.
