What is the weight limitation for flatbed trucks hauling pipe into state of California?

80,000 lbs. gross weight... same axle weights as anywhere else... 34,000 for a set of tandems, 40,000 for a ten foot spread, which is probably what the trailer it's being transported on would use, given California's bizarre 40' bridge limitation, versus the rest of the country's 41' bridge.

Be certain before you cross that state line that your trailer is California legal. A 48' trailer with a 10' spread axle should be - a 50' trailer with only a 10' spread would be over bridge.
