In this Aug. 2, 2010, file photo, a kite boarder sails along the Columbia River in Hood River, Ore. The Hood River-White Salmon Bridge is in the background.

The White Salmon and Hood River Bridge, built in 1924, has a weakening structure that is susceptible to heavy weight loads and trembles under traffic.

The Hood River-White Salmon Bridge received a federal grant toward replacing the 100-year-old span, which is named for the Oregon and Washington towns it connects.
