In the 1960s, London Bridge — yes, the one in the nursery rhyme — was taken apart in London and transported to Lake Havasu City, Arizona. It was painstakingly reconstructed and rededicated as a functioning bridge over Bridgewater Channel in 1971.
In 2015, T.R. Orr, Inc. was awarded a project to repair and maintain the bridge. Among the items to be addressed was a bearing chamber requiring repairs because it was flooded. Other items included new ladders and handrails to improve safety and improving the utility crossovers.
Due to the age and unique character of the bridge, this project presented many unique challenges, compounded by working in the confined spaces within the bridge. Among one of the more interesting challenges was completing the work without disturbing any of the bats thought to roost there. A formal bat survey determined that the maintenance project should not impact roosting bats, based on the location of the bats in relation to the project area.
