The City of Houston Office of Emergency Management (OEM) urges residents and visitors to avoid Houston roadways during periods of prolonged or intense rainfall. The Department of Public Works & Engineering and OEM have produced a map of roadway segments and underpasses that are especially prone to flooding. Travelers should heed special caution around these locations.
All intersections and underpasses have the potential to be dangerous during periods of heavy and/or prolonged rainfall. If you see a barricade in your path, DO NOT drive around it or move it. Barricades are put in place explicitly to protect lives.
