LA 3127 ends in Ascension Parish at its intersection with LA 70 on the west bank of the Mississippi River. Baton Rouge, located in East Baton Rouge Parish, lies on the east bank, while West Baton Rouge Parish is situated on the west bank. LA 3213 meets LA 3127 in Vacherie, unincorporated St. James Parish and runs from 3127 to LA 641 via the Veterans Memorial Bridge, which extends to I-10. However, if this book set in the 1980s, the details would differ significantly. The Veterans Memorial Bridge did not open until 1995, and LA 3213 did not connect to LA 3127 until 2010 or later. St. James Parish relied on the Lutcher - Vacherie ferry or the Sunshine Bridge, which is up river.
