Thanks. The bypass has only a State Route number (SR 1900), which it will keep until the bypass is complete, when it will be renumbered to US 74 (probably Bypass, since there is a US 74 Business in Shelby already).
We did not include the Sanford Bypass in the HB until US 421 was moved onto the bypass, even though the freeway connected NC 87, US 421 and US 1 for years. This is a similar case.
