Farm to Market Road 3248 (
FM 3248) runs around the western and northern portions of
Brownsville. FM 3248 begins at an intersection with
US 281 in Brownsville, heading north on West Alton Gloor Boulevard, a five-lane road with a
center left-turn lane. The road heads through residential neighborhoods before becoming a two-lane road and running between woodland within the
Lower Rio Grande Valley National Wildlife Refuge to the west and businesses to the east. The highway turns east-northeast and runs through more residential and commercial areas, crossing a
Union Pacific railroad line. FM 3248 heads into commercial areas as a five-lane road with a center left-turn lane and comes to an interchange with
I-69E/
US 77/
US 83. Past this interchange, the road becomes East Alton Gloor Boulevard and continues into areas of residential neighborhoods and businesses. The highway intersects
FM 1847 and becomes two-lane Dr. Hugh Emerson Boulevard, heading into unincorporated areas and passing through farmland with some homes. FM 3248 crosses back into Brownsville and comes to its eastern terminus at
FM 511. FM 3248 was designated on November 5, 1971, from what is now I-69E/US 77/US 83 southwestward to US 281. On September 5, 1973, it was extended eastward to its intersection with FM 1847, and again extended eastward on September 26, 1979, to its intersection with FM 511. The portion west of FM 1847 was redesignated
Urban Road 3248 (
UR 3248) on June 27, 1995. The designation of this section reverted to FM 3248 with the elimination of the Urban Road system on November 15, 2018. ;Junction list {{TXint {{TXint ==FM 3249==
