Opening in 1912, the Steel Bridge is not only the second oldest operating vertical lift bridge in the United States, but also the only double-deck bridge with independent lifts in the world. It carries road and Portland MAX light rail traffic on its upper deck and main line railroad traffic on the lower (with pedestrians on both). It is located just east of Union Station and was likely part of VC tower's span of control. It's actually a common misconception that downtown Portland sits on the Columbia River, when in fact it is on a tributary, the Willamette.
The bridge carries the MAX Red, Blue, Green and Yellow lines, with flat junctions at each end. Below MAX SD660 #309 on a Yellow routing diverges onto the North-South downtown alignment at the western junction.
Here SD660 LRV's #311 and #304 taking a green line routing into downtown at the west end of the double deck Steel Bridge.
Here SD660 #303 and #225 on a Red routing take the opposite path towards the east-west downtown alignment.
The Steel Bridge has a two lane truss containing both MAX tracks and two single lane wings on the side for road traffic.
The bridge is just downstream from Portland Pacific Grain Terminal.

MAX SD660 #252, in a 1980's retro paint scheme, sits in front of the Portland Trailblazers' arena at the Rose Quarter station just prior to entering east bridge jct.
Directly east of the Steel Bridge is EAST PORTLAND interlocking where the route to the passenger station splits from the Union Pacific Portland Sub. While there I caught this Union Pacific light engine move with ES44AC's #8114 and #7786.
EAST PORTLAND interlocking also functions as Portland Union Stations turning wye and every day Amtrak Train 28, the Portland section of Amtrak's eastbound Empire Builder Train 8, goes for a spin in order to head back west out of the station to reach the BNSF Columbia River route on the north bank. Train 28 consists of coaches, a sleeper and the sightseer lounge/cafe car, which will join with Train 8 in Spokane on the midnight after departure. Today, Train 28's power consisted of a single ALC-42 Charger, #310.
