Great Bridge Lock Replacement 2014
A crane is moving one of two refurbished lock gates off a barge and lowering it into the canal at the Great Bridge Lock Feb. 20, 2014. The 72-ton set of aging lock gates were removed after 25 years - part of a service plan to increase the lifespan of the Great Bridge locks. Each set of canal gates, which are managed and operated by the Norfolk District, is removed and refurbished on a rotational basis every 15 to 20 years.
