The first piece of US 17 ALT to be 4-laned was in 1970 from US 78 to I-26.
In 1974, US 17 ALT was 4-laned within the Georgetown City Limits.
In 1975, US 17 ALT was 4-laned on its US 52 duplex in Moncks Corner.
In 1979, US 17 ALT was 4-laned on its SC 63 duplex in Walterboro.
In 1988, US 17 ALT was 4-laned on its US 521 duplex west of Georgetown.
In 2001, US 17 ALT was 4-laned from I-26 to S-8-62 College Park Rd.
In 2007 or 2008, US 17 ALT was 4-laned from S-8-62 to US 176.
In 2014 or 2015, US 17 ALT was 4-laned from US 176 to S-8-9.
In 2016, US 17 ALT was 4-laned from S-8-9 to US 52.
Comment: US 17 ALT is no longer (if it ever was) a good viable alternative to US 17. It would make much more sense to have it redesignated as US 15 below Walterboro and US 701 from Walterboro to Georgetown.
US 17 ALT is especially slow through Summerville and Walterboro.
US 17 ALT has posted TRUCK routes in Summerville (uses SC 165 and SC 642) and Walterboro (uses SC 64, Robertson Blvd, and SC 303).
