State Highway 5, or SH 5, runs along the old route of U.S. Highway 75 at Howe into the city of Allen. SH 5 parallels US 75 along its length and runs alongside the former Southern Pacific rail lines. SH 5 was created in 1959 when the new route of US 75 was established to the west. Historically, SH 5 extended into and through Plano and Richardson.

Route history

The current version of SH 5 was established in 1959 initially as a replacement for the former routing of U.S. Highway 75 from Richardson north to McKinney when US 75 was rebuilt further to the west. The route was extended north to Howe in 1967 to replace another portion of US 75 that had been upgraded on a new route just to the west. Between 1987 and 2003, the southern terminus was moved northward as portions of the highway were returned to local cities: First, ending at SH 190 in 1987, then ending at the northern Plano city limit in 1988, and finally ending at the Exchange Parkway in Allen in 2003.

In 1926, U.S. Highway 385 was routed over SH 5 from New Mexico to Amarillo, and U.S. Highway 370 to Henrietta. While the routes were marked concurrently, the remainder of SH 5 kept its numbering until 1939, when SH 5 was truncated to a route running from Amarillo to near Dalhart. SH 5 was finally cancelled in 1944, only to be reassigned in its new location in 1955.

South of Dallas, US 75 was supplanted by Interstate 45, though US 75 retained its designation until 1987. When US 75 was decommissioned south of downtown Dallas, the segment from south of Corsicana to north of Houston was redesignated as State Highway 75.
