Jefferson County is getting a new type of interchange on Interstates 59 and 20 that will transform this exit in McCalla, according to an announcement from the Alabama Department of Transportation (ALDOT).
Construction on the county’s first “Diverging Diamond Interchange” (DDI) at Exit 104 at McAshan Drive. The exit will offer access to the Rock Mountain Lakes community and the Jefferson Metropolitan Park.
There are more than a dozen industrial campuses near this exit — such as the $1.1 billion JM Smucker Uncrustables plant — making this a traffic boon for locals and commuters alike.
Funding is coming from three sources: • $14 million — Jefferson County • $6 million — Federal Interstate Maintenance • $2 million — ATRIP-II (Rebuild Alabama Act funds)
The $22 million job was awarded
