Oops. A tactical operations vehicle from the Army Corps of Engineers had some tactical problems Friday morning when deploying for a training exercise along the Willamette River in downtown Portland.

Namely, the driver missed the ramp off Naito Parkway to drive under the bridge trestle and his truck, a mobile emergency operations center, became wedged under the bridge.

The obvious engineering solution: deflating the tires and backing out. They tried that. Then the truck's transmission failed.

Portland Police eventually called a tow truck to rescue the Corp's mobile emergency operations center from its mobile emergency. Traffic was briefly interrupted on Naito Parkway.
