The most highly traveled bridge in Washington state – I-90 across Lake Washington -- is also one considered to be structurally deficient.
According to a new analysis by the American Road and Transportation Builders Association, 4.8 percent of bridges in the state are structurally deficient.
That doesn't mean a bridge is unsafe for traffic, but that it has at least one significant defect.
For instance, I-90 earned a poor rating for anchor cable deterioration. Money has been budgeted for a fix and work is currently underway.
The report has been issued by the American Road and Transportation Builders Association -- a trade group representing builders – for the last five years.
In it, Washington is among the safest in the country. Of the 8,233 bridges in the state, 399, or 4.8 percent, are classified as structurally deficient.
But a portion of SR 520 over 116th Street in Bellevue makes the list of deficient bridges for some deck deterioration.
President Trump said in his State of The Union speech he wants Congress to approve $1.5 trillion on infrastructure.
The Washington State Department of Transportation says any bridge listed in poor condition is immediately put on a priority list for their Bridge Preservation Program.
The state has identified needed repairs on 4,979 bridges which the state estimates will cost $28.1 billion.
