The (Crappy) Bridges of Los Angeles County

We all saw the tragedy in Minneapolis earlier this week when the bridge collapsed.

Now the folks at MSNBC.com have assembled a list of bad bridges.

The list has over 500 entries for LA County, and over 200 in the City of LA itself.

Some lowlights:

D 31.5 SANTA MONICA LOS ANGELES PACIFIC COAST HWY(BLUFF) 0.1 MI S PCH
D 55 10 LOS ANGELES LOS ANGELES I 110 07-LA-010-14.75-LA
O 61.1 LOS ANGELES LOS ANGELES OLYMPIC BLVD AT OLYMPIC BLVD
O 62 101 LOS ANGELES LOS ANGELES I 405 & N101-S405 RAMP 07-LA-101-17.14-LA

Keys to using the data:
Status of “D” means the bridge has been rated structurally deficient; “O” means it has been rated functionally obsolete.

Sufficiency rating is a value obtained by calculating four separate factors (structural adequacy and safety, serviceability and functional obsolescence, essentiality for public use, and special reductions) that is indicative of a bridge’s sufficiency to remain in service. A value of 100 represents an entirely sufficient bridge and a zero represents a deficient bridge.

The raw dataset of the National Bridge Inventory, which is compiled by the U.S. Department of Transportation’s Federal Highway Administration from state reports, used for analysis was provided to MSNBC.com by the National Institute for Computer-Assisted Reporting at the University of Missouri. The most recent data includes inspections through December 2006.

Which deferred maintenance deathtrap do you drive on?
