I was doing some future roadtrip planning through Mississippi, and was curious why the US business routes in Natchez and Vicksburg weren't in the HB? I know that most of these are not signed at their endpoints with their parent routes (with one exception). However, all of them are signed well enough that their routes are discernable.
Signs for US61Bus in Vicksburg are found at the
north end and
(essentially) south end. US80 Historic is also signed EB at the aforementioned link and
westbound. Unfortunately, no signage at the or near the junction indicating its turn.
Signs for US61Bus appear in Natchez on
St. Catherine St, the turn at
MLK St, and turn at
Homochitto St. US84Bus is also on St. Catherine then Jefferson, with signs WB at the turn onto
Canal St, and EB at the turn onto
Franklin St.
