Mileage and exit numbers

Need up-to-date mileage after the truncation. --Gooday.1 01:33, 18 April 2006 (UTC)[reply]

I'm just curious about why there is an exit column. When I converted the table to templates, I retained it, but if there are no numbered exits, it should be removed. To remove it:

Remove the |exit from all of the templates and optionally remove the |exit= from each template.
If there are exits, but they are all unnumbered, add |unnum=yes to the {{jcttop}} which will add the "All exits are unnumbered." note above the table.

If there are numbered exits along this highway, please add the missing numbers. If there are a mix of numbered and unnumbered exits, the unnumbered ones can have an em dash (—) entered for the missing number, leaving the non-exits to have blank cells in the table.

I believe it I put it there at the time in case there were exit numbers, but this highway never exhibits a freeway behavior, so it can be removed. --WashuOtaku (talk) 12:40, 28 May 2012 (UTC)[reply]

US521 CONN does not exist

Sometime prior to 2009, the section marked as "US521 CONN" in Sumter became the main route, rather than the route thru downtown. See SCDoT highway map for 2009 (and years following). This means the table is incorrect for the section thru Sumter, and probably all the mileages are wrong. Note that Google Maps is also wrong (one has to assume the SC Dept of Transportation is more accurate than Google...).
