Two Brownsville residents told the Cameron County Commissioners Court on Oct. 7 that traffic linked to SpaceX shift changes has created frequent, dangerous backups on Highway 4 and FM 511 and that heavy flows are spilling into neighborhood streets.

“Traffic is dangerous in our neighborhoods,” Rene Medrano said during the public‑comment period, citing repeated accidents at the intersections of Highway 4 and FM 511 and North Oklahoma and FM 511. Medrano said drivers are detouring through residential streets, using shoulders and veering onto grass to make turns during congestion.

Marcela Vargas (recorded in the meeting as Marcela Cope) said she witnessed a crash involving a state trooper the previous day and said residents have reported near‑daily incidents on the Boca Chica/511 corridor. “We need some traffic lights for God’s sake for right now,” she said, and also said the roadway is dark at night and children on school buses are affected.

Both speakers said SpaceX provides two parking lots but that the influx of vehicles is nevertheless spilling into nearby subdivisions and county roads that are narrower than state‑maintained highways. Medrano asked the court to take up the issue in executive session; the court did not take immediate action during the meeting.

No formal county action or motion to study specific fixes was made on the record at the Oct. 7 meeting. Commissioners did not announce a follow‑up at that time; county staff or the court could be asked to report back with traffic data, enforcement coordination with state agencies, or temporary mitigation such as signage or traffic control in the affected neighborhoods.
