Our Practice Focuses on Bridge Architecture and Aesthetics
Our Practice Focuses on Connecting Communities
Bridges are civic art, community connectors, and cultural attractions as much as they are about functional urban infrastructure. We work with our teams to elevate people’s experience both using bridges and when viewing them from afar. What we do:
- Architectural renderings, visualizations, architectural models
- Community integration and public processes
- Design elements – railings, abutments, bicycle bridges and pedestrian paths
We have a long track record working with world-class cities, engineering partners, and public agencies to navigate complex regulatory, entitlement, and public engagement processes for major infrastructure works. Our solutions provide for vehicular and non-motorized access, universal design and accessibility, respond to local context; and comprise the latest technical solutions, sustainability and innovation.

Tilikum Crossing: Bridge of the People: Portland’s Bridges and a New Icon
Portland, Oregon’s innovative and distinctive landmark, Tilikum Crossing, is the first major bridge in the U.S, carrying trains, buses, streetcars, bicycles, and pedestrians- but no private automobiles. When regional transportation agency TriMet began planning for the first bridge to be constructed across the Willamette River since 1973, the goal was to build something symbolic, which would represent the progressive nature of the Twenty-First Century. In this book, the award-winning architect of Tilikum Crossing, Donald MacDonald, and co-author Ira Nadel, tell the story of Portland through its bridges. Written in a friendly voice, readers will learn how Portland came to be known as “The City of Bridges” and the home to this new icon in the city’s landscape.

Bay Bridge: History and Design of a New Icon
An innovative landmark a quarter-century in the making, the new eastern span of the San Francisco–Oakland Bay Bridge represents the latest spectacular chapter in the history of this storied structure. The new bridge’s architect, Donald MacDonald, teams up with author Ira Nadel to create this illuminating book. With friendly text and charming illustrations, Bay Bridge reveals the design decisions that have shaped the evolution of the bridge over the last century—from the history of the original bridge, through the planning of the new span, to the construction of its signature 525-foot-high white tower. In the same elegant package as Golden Gate Bridge and Alcatraz, this volume makes a lovely souvenir for San Francisco devotees, architecture buffs, and tourists.

Golden Gate Bridge: History and Design of an Icon
Nine million people visit the Golden Gate Bridge each year, yet how many know why it’s painted that stunning shade of “international orange”? Or that ancient Mayan and Art Deco buildings influenced the design? Current bridge architect Donald MacDonald answers these questions and others in a friendly, informative look at the bridge’s engineering and 70-year history. This accessible account is accompanied by 70 of MacDonald’s own charming color illustrations, making it easy to understand how the bridge was designed and constructed. A fascinating study for those interested in architecture, design, or anyone with a soft spot for San Francisco, Golden Gate Bridge is a fitting tribute to this timeless icon.

CEREMONY MARKS BEGINNING OF GOLDEN GATE BRIDGE SUICIDE WORK
A big step was taken to save lives at the Golden Gate Bridge.
Local officials gathered at the span for a ceremony at the bridge Thursday to mark the beginning of work to line both sides of the bridge with a suicide barrier.
“Where nets have been erected they’ve been incredibly effective. Nets have been installed on many bridges throughout the world over the last two decades and there’s only been one fatality at one of those installations,” Golden Gate Bridge Highway & Transportation District General Manager Denis Mulligan said.

THE BRIDGE THAT BANS CARS
You can walk, bike, or ride a bus across Tilikum Crossing in Portland—but you can’t drive.
If you stand in the middle of the new Tilikum Crossing bridge over the Willamette River in Portland, Oregon, you may see many things whiz by bikers, joggers, light-rail trains, streetcars, buses, even ospreys and bald eagles from a nearby wildlife refuge. You will not, however, see any cars.
The Tilikum, which took four years to construct, is the first long-span bridge in the United States to accommodate so many ways of getting from one side to the other while banning automobiles. The span follows—and shares certain characteristics with—a spate of high-profile pedestrian-bridge projects, including the Bob Kerrey Pedestrian Bridge between Omaha, Nebraska, and Council Bluffs, Iowa, completed in 2008…

STATE ACCELERATES SIGNATURE BRIDGE
Miami’s notoriously crowded streets have become the road less traveled with the sweeping impact of the Covid-19 pandemic.
With most businesses, stores and shops shut down and social distancing being preached and practiced, the highways and byways are seeing meager traffic in comparison with the bumper-to-bumper of not so long ago.
The governor and state transportation department see this rare unfolding event as an opportunity to speed up road construction projects, including the new Signature Bridge rising in downtown Miami…

UNIVERSITY OF OKLAHOMA AMERICAN SCHOOL ARCHIVE RECEIVES SIGNIFICANT DONALD MACDONALD COLLECTION
The American School Archive, part of the University of Oklahoma (OU) Libraries’ Western History Collection, recently acquired the Donald MacDonald Collection, including thousands of items representing the life’s work of prominent San Francisco-based architect Donald MacDonald, FAIA (b. 1935).
MacDonald (b.1935), who was born in Canada, chose to study architecture at the University of Oklahoma after seeing a photograph of Bruce Goff’s work. He studied with Herb Greene at Oklahoma and later earned a master’s degree from Columbia University. He has said that the level of freedom he was given in Herb Greene’s design studios at OU fundamentally shaped his vision of the creative process as central to an architect’s practice.
It was MacDonald who gave the name “The American School” to the pedagogy and practice that emerged at the University of Oklahoma in the mid-century under Goff and Greene. After finishing his master’s degree, MacDonald opened his own private practice in San Francisco…
