or '''F.M. 1419''' is a farm to market route starting in
Brownsville, Texas and ending east of Brownsville. It is possibly the southernmost numbered route in the Texas Highway System. The route coincides mainly with Southmost Blvd. within the city limits.
The route was initially designated in 1949 from where the intersection of F.M. 511 and Southmost Blvd intersect, traveling southeastward to the intersection of South Point. Later that year it repalced the section of 511 from the Southmost Blvd intersection northwestawrd to it's intersection with State Highway 4. In 1955 it was again extended, this time eastward and northward to where the road again intersected SH 4, which is the current designation.
Technically, the stretch from the intersection with F.M. 511 northwest to SH 4 was redesignated in 1995 as an Urban Road.
