Narrative and photographs
Continuing our stroll eastward along Old Seven Mile Bridge, Rich spotted U 278, the next mark in the line after V 278. This disk is also in very good condition and is set in the north curb of the bridge. The two mile walk from Pigeon Key back to Knights Key offers plenty of time to reflect on the engineering marvel of the bridge, and the fact that this extremely narrow span once carried a two-lane highway!
