Booth-Kelly Railroad Bridge (1882), now called Hayden Bridge, is a single span Whipple through truss spanning the McKenzie River in Springfield. A Whipple truss is a (stronger) variation of the Pratt truss, also called a “Double Intersection Pratt”, characterized by diagonal tension members crossing adjacent verticals, thereby spanning two panels instead of just one for the Pratt truss. It is considered the oldest surviving bridge in Oregon, while rare and significant for its wrought iron Phoenix columns. This bridge has been moved once. Originally built in 1882 by Phoenixville Bridge Works at Corrine, Utah, it was dismantled and relocated in 1901 to its current location to serve the since abandoned Weyerhaeuser Logging Railway. The bridge was abandoned in 1987, then decked for pedestrian use and reopened in 2019. Notable also is the use of longitudinal bracing rods beneath the bottom chord bracing the deck beams.

Grad students Donghwan Jeon and Saturnino Garcia took top honors in the Computer Science and Engineering category at Research Expo for their poster "Kremlin: Like Gprof, but for Parallelization."
The steel roof of OCP was developed rapidly at the end of the project after a change in brief removed the need for a solid concrete roof. I was very pleased with the result which I hope will be simple an elegant.
The primary structural element is the central concrete column. The steel connects at the head with a moment connection, stiffening the column into double curvature during typhoons. As a result the perimeter steelwork is lightweight, allowing better views out to the Ocean Park.

As the viaducts of the South Island Line pass through dense urban areas we were asked to design noise barriers along much of the length. With Aedas, Atkins developed an integrated solution that supported the overhead lines supplying power to the trains, allowed hot air and smoke from any fires to vent out and gave views out for the passengers.
Hopefully also it is also interesting to look at from outside. It is difficult to hide a viaduct but we came up with a gradated green tube of glass and metal facets that then shifts colour as it enters the two stations - which each have their own colour.

As the viaducts pass through Ocean Park and Wong Chuk Hang Stations and on to Ap Lei Chau much of their length is shielded by glazed noise barriers. These also support the Overhead Power Lines for the trains.

Earl Blumenauer Bicycle and Pedestrian Bridge (2022), is a tied-arch type bridge design spanning the Interstate 84 freeway in Portland, Oregon, USA. The bridge is aligned with NE 7th Avenue, connecting neighborhoods in Northeast Portland for bicycle and pedestrian users, but not for vehicular traffic. The design does accommodate use by emergency vehicles in the event of some catastrophic or seismic emergency. Previously known during design development as Sullivan’s Crossing, the bridge was dedicated and named for Congressman Earl Blumenauer, advocate for rail and streetcar mass transit, and promoter of commuting by bicycle. Construction was completed in 2022.
