Perrysburg, Ohio, USA has three streets named Boundary. We have East, West and South Boundaries. South Boundary is further clarified by East Boundary and West Boundary. All the streets in the old section of town are designated East or West of the main drag. This is needed because all the East-West streets are numbered both ways from Louisiana Avenue, the aforementioned main drag, and so we have a 100 block of East Third Street and a 100 block of West Third Street. This puzzled me when I moved here until I learned that Perrysburg is the only city besides Washington DC that was laid out by the Federal government.
Nearby Toledo is frequently said to have the highest numbered street in the country. I think it's 235th or so, but I don't get out to that neighborhood much.
Fair winds and plain sailing,
