Hwy 21 actually starts at the intersection of Gravois Rd (Hwy 30) and Tesson Ferry Rd. in Affton, MO, near Grant's Farm. Long known as "Blood Alley" due to the hilly (frequently blind) turns and heavy traffic, it's mostly been tamed by replacing it with a four lane limited access highway from Lindbergh Blvd (US 61/67) in S. Saint Louis County to Hillsboro in Jefferson County (about 26 miles). However, the old Hwy 21 still exists. Heading southbound, take the "Old Route 21/Meramec Hts" exit just past Hwy 141. The "official" Hwy 21 rejoins in Hillsboro at Route B. And if you're feeling adventurous, Hwy 21 continues another 115 miles to the Arkansas state line, where it turns into Arkansas Hwy 115.
