A damaged girder on the Interstate 90 Front Street overpass will be replaced later this year, according to the results of an investigation by state-employed bridge engineers in the aftermath of a March 13 accident.

More than one month ago, the hydraulically lifted bed of a truck owned by city waste services contractor Recology Cleanscapes collided with the overpass, sending the driver to the hospital and prompting a bridge inspection from the Washington State Department of Transportation.

The immediately apparent damage to the bridge from the accident was a large hole in the south face of the overpass that penetrated both the concrete and, according to WSDOT, a girder.

The rightmost eastbound lane of the overpass remains closed to truck traffic.

“By our estimate, it will cost $1.2 million to replace the damaged girder,” WSDOT Assistant Regional Administrator Dave McCormick said.

The Department will fund the replacement with emergency money from the United States government until it can be compensated for the overpass damage.

WSDOT is seeking compensation from Recology Cleanscapes’ insurance provider.
