Creation: Extended to South Carolina in 1965, as an addition to US 1-78, then as an addition to SC 125 to Beech Island, then replacing SC 28 to barnwell, Hampton, and Varnville; then replacing SC 128 to Ridgeland; then replaced SC 462 over to the Bluffton area; then replaced SC 46 onto and around Hilton Head Island.
|
Adjustments: Note that between 1963-66 the primary highway on Hilton Head Island was removed from today's S-7-44. It is not clear it the route was SC 46 or US 278 at that time.
Official maps through the mid-1970s showed US 278 turning south to Forest Beach. However, no Beaufort County map shows anything other than S-7-80 on Pope Rd, so I have big doubts if US 278 ever used Pope Rd south to the waterfront. In 1998, US 278 was rerouted at Ridgeland to follow US 17 south to nearly Hardeeville, then east as an upgrade to S-27-88 and S-27-141 to meet back up with US 278 at the SC 170 jct. The old route out of Ridgeland became extensions of SC 336 and SC 462, plus SC 170 remained from their previous overlay. Also in 1998, US 278 was given a toll bypass of a huge chunk of Hilton Head, leaving behind US 278 Business. Both routes now end at each other.
Improvements: Fully paved upon designation. The first multilane sections of US 278 were in place when designated: The US 1-78 multiplex; the SC 125 multiplex; the SC 64 multiplex in Barnwell The next section to be upgraded was from Allendale to Fairfax, in 1977. In 1980, US 278 was 4-laned in the SC 46 vicinity and on everything east of the bridge to Hilton Head. In 1987, US 278 was fully 4-laned east of SC 46. In 1990, US 278 was 4-laned between SC 170 and SC 46. When US 278 was rerouted in 1998, everything east of US 17 became 4-laned including the toll bypass. Comment: US 278 provides the only road access to Hilton Head Island, which today is a thriving resort area and is also the largest town in South Carolina in terms of area. US 278's toll road was the first toll road in South Carolina in many years. The last one I can think of is today's SC 171 below SC 700, which was toll up to at least the 40's. US 278 skims across the top of the Savannah River Site. Activity at the site is a lot of cleanup and restoration, so perhaps one day US 278 could be routed through the site instead of around it, especially since some of the roads in the interior of the site are 4-lane. US 278 was blown off by I-95 until the mid 1990's when a new interchange was built (SC 336 exit today). | |||||||||||||
