Portland-Milwaukie Light Rail Bridge
The Portland-Milwaukie Light Rail Bridge will serve light rail trains, pedestrians, cyclists, and in the future, Portland Streetcar. Bus lines 9, 17 and 19, which currently travel on the Ross Island Bridge, may also change routes to use the new bridge (Decisions about bus line planning in regards to the entire project will occur through a service planning public process). The bridge will not serve private vehicles, but will be able to accommodate emergency vehicles.

December 2013–February 2014
At the West Tower site, bridge deck construction continues in each direction with the help of form travelers; as the deck lengthens, permanent cables are being installed. Construction of the west span between the abutment and the landside piers is complete and the track slab will be added once the bridge deck is complete. By the end of December 32 bridge deck segments and 9 permanent cables will be complete. By the end of February all permanent cables will be complete on the west and the landside closure on the west could be complete.
The Eastside Greenway Trail continues to be closed until June 30, 2014 to allow for the east span between the abutment and landside piers to be installed. Wall installation is mostly complete and trail reconstruction will occur once the east span is complete. The detour for pedestrians and cyclists is SE Water Avenue with new sidewalks and bike lanes and a connection directly to SE 4th Avenue and the Springwater Corridor.
