and immediately enters St. James Parish. Undivided, two lanes, and largely secluded for the first several miles, it heads eastward and intersects LA 3219
near the community of St. James. Near Vacherie
, it intersects LA 20
. Continuing eastward, the route crosses into St. John the Baptist Parish
before a junction with LA 640
south of Edgard
. As LA 3127 crosses into St. Charles Parish
, the highway turns toward the southeast. Shortly afterward, it divides and expands to four lanes. Access to the river communities of Killona
, Taft
, and Hahnville
as well as many chemical and industrial vacilities are provided via junctions with LA 3141
, LA 3142
, and LA 3160
, respectively.
The final few miles of LA 3127 consist of a duplex with I-310
, beginning at Exit 10. Both highways end at signaled intersection/interchange with US 90 just west of Boutte
. As US 90 is slated to be upgraded to interstate standards (as Interstate 49
), there are plans to massively reconfigure both the interchanges.
An extension of LA 3213 (which crosses the Mississippi River via the Veterans Memorial Bridge) to connect with LA 3127 opened in June 2008. This junction is between LA 20
and LA 640
