Bridge and lock tenders assist business and recreational vessels in navigating inland rivers. Many boats are too large to fit beneath some bridges. It is the bridge tender's job to follow the protocols and operate the machinery required to open bridges safely. This includes halting land travel as well. The tender closes the bridge after the boat has passed through, making sure to properly lock it back in place. The tender then enables traffic to continue on the bridge. 

Canal locks are used to raise or lower water levels, allowing boats to transit through places of varying elevation. Lock tenders are responsible for opening and closing gates as well as operating the pumps. Bridge and lock tenders must be conscientious and dependable employees. They must be able to read and follow written directions. Maintenance and minor repairs may necessitate the use of tenders. 

Applicants must possess a high school diploma or GED. Most businesses prefer candidates with extra experience in electrical or mechanical machinery, as well as familiarity with a number of hand and power tools. Boat knowledge is a great advantage. The majority of tenderers are government personnel. The work might be full-time or seasonal, depending on boat traffic patterns. It can also be lonely and necessitate working outside in all weather conditions. Although it is not a glamorous job, a bridge or lock tender is a critical part of America's transportation system.
