Abstract

From September 16 to September 21, 1997, the Oregon Department of Transportation closed the northbound portion of the Interstate-5 Columbia River Bridge between Vancouver, Washington, and Portland, Oregon, to repair a cracked trunnion. The traffic management plan was based upon the development of a reversible travel lane on the three-lane, southbound span of the bridge. The reversible lane was designed to provide two travel lanes in the peak direction of flow, southbound in the morning and northbound in the afternoon. In addition to the reversible travel lane, other traffic management strategies that were included in the traffic management plan were high occupancy vehicle lanes, increased public transit service, Amtrak commuter train between downtown Vancouver and downtown Portland, and commercial truck access and route changes.
