This is done to insure safety, and toavoid tearing out the masonry should any ac-cident .happen to the pipe. The pipe is bricked inbetweenthe walls of the culvert. A protection has been provided extending 10 ft. from theface of the wall, which is designed to prevent any obstructioninterfering with raising the gate.
