DE 286 is 1.73 miles long and MD 286 is 2.09 miles long. The routes combined are only 3.82 miles long, still relatively short. Also the histories are related, as DE 286 was essentially signed as a continuation of MD 286. Dough487201:12, 18 January 2014 (UTC)Reply
Neither route is less than a mile long, which is my length criterion for merging routes. The only relation in their histories is that DelDOT decided to give the Delaware route the same number in the 1990s. MD 286 has been around since the 1930s and did not connect to the state line until the 1960s. This seems to be merging two route articles for the sake of merging two route articles.

A mile is just an arbitrary distance. The way I see it: if there were no state line, would the history have likely been similar? In this case, probably, with the obvious exception that 286 would have been extended all the way to 15 in 1960-1961. --NE217:49, 20 January 2014 (UTC)Reply
