Tilikum Crossing, Bridge of the People
A vital element of the Portland-Milwaukie Light Rail Transit Project is a new bridge across the Willamette River, the first span built over the river since the addition of the Fremont Bridge in 1973. Named Tilikum Crossing, Bridge of the People, this bridge will be distinctive in the United States, designed to carry light rail trains, buses, cyclists, pedestrians and streetcars, but not private vehicles. However, emergency responders will be able to drive on it if necessary.
From a distance, Tilikum Crossing, Bridge of the People, may look complete, but construction continues. Through 2014, crews will install rail for the trackway, the overhead electrical system that delivers power to the light rail vehicles, handrails for the multi-use paths, and barriers between the trackway, bridge cables and the multi-use paths. In 2015, expect to see light rail vehicles, streetcars and potentially buses on the bridge before the opening date while testing and the training of all transit operators occurs.
The bridge will open for use with the start of light rail service in September 2015.
The bridge has a cable-stayed design, with two piers in the water. A cable-stayed bridge is a bridge that consists of one or more towers through which cables are strung to support the bridge deck. Cable-stayed bridge types are efficient at spanning long distances while allowing a reduction of the number of piers in the water. Such bridges also can be designed with thinner decks than other bridge types, making possible a more transparent structure and a greater vertical navigation clearance.
The bridge name is Chinook Wawa, an international language used by first Oregonians, and later spoken by explorers, fur traders, settlers and the first few generations of Portlanders. Chinook Wawa is still spoken today. Tilikum means people, tribe and relatives, and has come to mean friendly people and friends.

From June 15, 2011, through September 30, 2014, a slow/no wake zone will be in effect to ensure the safety of Willamette River users and construction workers. Beginning July 1, 2011, an exclusion area around the in-water bridge construction site goes into effect.
