24.4 miles in length, Texas State Highway 4 (SH 4) links Downtown Brownsville with Boca Chica State Park along the Gulf of Mexico. Initially following International Boulevard from Downtown, SH 4 turns east at SH 48, overlaying Boca Chica Boulevard for its remainder to the state park. The state highway also serves interests to Brownsville-South Padre Island International Airport (BRO).

| SH 4 east next meets U.S. 77 Business (Washington Street) north. U.S. 77 Business (BU 77-Z) represents a portion of the former routing of U.S. 77 & 83 through downtown Brownsville. U.S. 281 also ended here but has since been pulled back to its current end along U.S. 77 Business north of Downtown. This assembly was modified sometime before 2011 to reflect this change. 02/19/06 |

| FM 1419 (Oklahoma Avenue) branches south from SH 4 (Boca Chica Boulevard) to South Point. The farm to market road then curves west to Southmost and Brownsville, meeting SH 4 (International Boulevard) prior to IH 69E. 02/19/06 |

| International Boulevard passes underneath the I-69E / U.S. 77-83 mainline in this scene. This was the ending point for SH 4 until 1997 when the state designation was extended into downtown Brownsville. 02/19/06 |
|
| IH 69E along with U.S. 77 & 83 travel south one mile to University Boulevard and the international border with Mexico as SH 4 continues west on International Boulevard. SH 4 overlays the pre-1997 alignment of U.S. 77-83 prior to their extension to the border. 02/19/06 |
