State Highway 48 or SH 48 runs from Brownsville to Port Isabel in Deep South Texas.

Route description

SH 48 begins at an intersection with Business Route 77 and the southern terminus of U.S. Route 281 on the west side of Brownsville. the road travels east through Brownsville on Boca Chica Boulevard, intersecting I-69E/US 77/US 83. It turns northeast at an intersection with SH 4 and past the Port of Brownsville (the former routing travels through the port grounds). The route then travels across the sandy flats near the coast of the Gulf of Mexico, before reaching its eastern terminus at SH 100 on the far northwestern edge of Port Isabel.

Route history

SH 48 was originally designated by 1926 from Daingerfield east through Linden to Atlanta as a renumbering of a portion of SH 1A. By 1930, this route was redesignated as an extension of SH 47. SH 48 was instead routed from Pharr through Harlingen to Brownsville, along the current route of U.S. Highway 83 (then U.S. Highway 96). In 1936, this route was swapped with SH 4, which ran closer to the Rio Grande along Military Highway, and was extended east out of the city to the Port of Brownsville. In 1938, it was replaced by US 281 except for the section from Brownsville to the port. In 1990, it was officially extended 15 miles (24 km) to near Port Isabel, replacing Farm to Market Road 1792, although some maps have this occurring by 1975.
