Work crews are scrambling to reopen the main highway that connects Tijuana to to Cabo San Lucas at the tip of Baja California Sur. Last week's rains washed out bridges and closed the road.
The highway is the only way for trucks, buses and cars to travel the length of the Baja California Peninsula.
The downed bridges have cut off thousands of people who live in small Baja California communities south of Ensenada.
Many people who were traveling south are stranded in Ensenada.
Johhny Friday runs a whale watching outfit in Laguna San Ignacio. He's stuck in San Diego. Friday's getting reports from bus and truck drivers and a friend who ventured out in a four wheel drive. "He said he passed several hundred cars and semi-trailers and its just stacked up. I find that Baja is probably the best place to ever get stuck. You find communities that'll really help out."
Friday says work crews are building bypass roads.
Meanwhile, Baja California's governor has declared an emergency in the area to free up funds for rebuilding.
