T.Y. Lin International of Beaverton, OR has earned an Honor Award for exemplary engineering achievement in the American Council of Engineering Companies’ (ACEC) 50th annual Engineering Excellence Awards (EEA) for the Sellwood Bridge Replacement in Portland, OR.

The new bridge carries two vehicular lanes, two bike lanes, two shared-use sidewalks, and will accommodate future streetcar service.
