Deficient major bridges in Oklahoma

MSNBC - Updated: 11:24 p.m. CT Aug 2, 2007

The following state bridges carry at least 10,000 vehicles a day and have been rated as either structurally deficient or functionally obsolete by inspectors, according to an MSNBC.com analysis of the National Bridge Inventory.

A structurally deficient bridge is closed or restricted to light vehicles because of its deteriorated structural components. While not necessarily unsafe, these bridges must have limits for speed and weight.

A functionally obsolete bridge has older design features and, while it is not unsafe for all vehicles, it cannot safely accommodate current traffic volumes, and vehicle sizes and weights.
