New Hampshire Highway System - Signage Practices - U.S. Highways

U.S. Highways

New Hampshire uses the standard issue U.S. Route shield, a six-point white shield over a black square background. New Hampshire does not use elongated route shields for U.S Routes, except on the occasional guide sign from a freeway. Alternates of U.S. Routes in New Hampshire are signed as state routes, with two exceptions: U.S. Route 1 Bypass and U.S. Route 3 Business. US-1 Bypass is signed in a similar fashion to Route 28 Bypass, a standard US-1 shield with the word 'BY-PASS' over the numeral. US-3 Business is unsigned, as it is completely overlapped by other routes.
