Journal of the Association of Engineering Societies . Fig. 8. Bridge at North Woodstock, // I bi&> EARLY AND CURIOUS TYPES OF CANTILEVER BRIDGE. 39 that this and the two following bridges, all in New Brunswick, weremade in England. The bridge over the north branch of the Oromocto River, nearFrederickton, X. B., 154-foot span, was the best sample of thelot, having separate chords for lever and arch and provision forexpansion. It was in use till about 1895 ! and it is my impressionthat it was then swept away by a freshet and log jam. The bridge over the south branch of the same river, Fig. 4,100-foot span, was unlike all the others in having both levers andarches above the roadway. It had separate chords for arch andlever and provision for expansion. I have no record of the lifeof this bridge. A highway bridge, Figs. 5 and 6, was erected at West Con-cord, Mass., over the Assabet River in 1869, and was in use as lateas 1899, when it was replaced by a concrete arch designed by R. Worcester, who can tell the condition of the old bridge afterthirty years service. M
