Mex 1 Full-Length Post-Hurricane Survey


Photo temporary road repair, Baja California Sur, Mexico.

The worst post-Hurricane Juliette hazard remaining on Baja's main highways is this temporary bridge crossing about 27 miles south of Todos Santos, Baja California Sur, Mexico. See text of article.


By Gene Kira, Oct. 28, 2001, as published in Western Outdoor News:

A full-length survey last week of Baja California's Mex 1, the Transpeninsular Highway, showed road conditions generally excellent from the border south to Mulege, but still feeling the effects of last month's Hurricane Juliette from there to Cabo San Lucas.

Large crews with heavy equipment were working to widen the roadbed in many places, and new pavement was being laid down in many sectors. The entire highway, including both the East Cape and Todos Santos southern branches from La Paz to Cabo, was passable by busses and heavy trucks.

Following here are section-by-section observations taken late last week. Unless otherwise noted, Baja road conditions observed were "normal" for Mex 1, including sections with narrow, no-shoulder roadbeds, sharp edge drop-offs, occasional potholes, small edge erosion, concrete culvert lintels very close to the pavement edge, and other miscellaneous road hazards that may require caution. Mileages given are approximate. Unless otherwise noted, all detours and dirt filled crossings were found to be passable with care by most vehicles.

- TIJUANA TO EL ROSARIO: Generally excellent condition to about 20 miles south of El Rosario. Wide and smooth with newly painted center and edge lines.

- EL ROSARIO TO CATAVINA: Numerous short stretches of moderately roughened pavement. Numerous small areas of edge erosion going a few inches inside edge line. Overall condition good.

- CATAVINA TO LAGUNA CHAPALA: Not new, but in good condition. Some stretches of slightly roughened pavement. Had to look hard to find six small "potholettes" about 14 miles south of El Rosario.

- LAGUNA CHAPALA TO GUERRERO NEGRO: At 14 miles, some potholes and slightly roughened pavement. Generally in good condition.

- GUERRERO NEGRO TO MULEGE: No unusual problems.

- MULEGE TO LORETO: Many small to moderate areas of edge erosion from here south to Cabo San Lucas. Two small dirt filled sections leaving town. A little lumpy for very low clearance vehicles, but busses and trucks passing through.

Mile 5: 100-yard detour. Rocks on edge of road.

Mile 12: 50-foot dirt fill.

Mile 20: 40-foot dirt fill. Bumpy with small rocks.

More instances of the same at miles, 30, 31, 42, 57, 59, 63, and 75.

Mile 18: 100-foot dirt fill with 3 inches of water flowing over rough pavement.

Mile 20: Edge erosion requires caution.

Mile 24: 100-foot gravel fill with 1 inch of water on road. Hard bottom. Another dirt fill closely following.

Mile 26: 1 inch of water flowing across blacktop.

Mile 27: One-third mile dirt fill. Very dangerous pipe and steel plate temporary bridge at south end. Use extreme caution. Note two wide gaps running parallel to roadbed in center of road. All vehicles crossing, but watch it.
