A project that we (Hannah Reed/PBA) worked on for any years, and obtained planning permission twice, but sadly we were bumped off the project before start of construction by a cheaper designer. The new office building sits on the site of Shakespeare's first London theatre, the remains of which are preserved beneath the floor.
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.

Engineers put the replacement bridge for the Bailey Bridge in Irvine in place. The Bailey Bridge was based on a World War II design and crossed the River Irvine from the early 70s until it was demolished in the spring of 2009.

Builders wait for the order to tear down the building.

Armitage Bridge (1887), also called Coburg Railroad Bridge and McKenzie River Railroad Bridge (historically, John Day Railroad Bridge), is a single span Whipple through truss bridge over the McKenzie River, between Eugene and Coburg. This bridge has been moved once. Originally erected in 1887 across the John Day River at the confluence with the Columbia River, it was dismantled and relocated here in 1907 by the American Bridge Company for new owners, Southern Pacific Railroad. This bridge was designed by prominent American civil engineer and great bridge engineer, George S. Morison, who designed many major bridges, some of similar configuration to this one. The bridge is made of wrought iron, pin-connected, and riveted throughout, making it one of the few remaining bridges of its era. Further, while this bridge was a relatively small project for Morison, it remains one of the few surviving Morison bridges of this distinctive configuration. Notable features are the deep lattice portal bracing, mid-height horizontal beam in the end panels and cast-iron decorative details, like the date plate. Lane County, Oregon, USA.
