Interview With Amy Squitieri

Amy Squitieri of Mead & Hunt

If there is a slogan which best describes a pontist and a preservationist, it would be this: We breathe new life into bridges when they can no longer support the increasing amount of traffic. We maximize their usage so that other forms of transportation, such as bike and foot traffic, can benefit from it. We make sure that its history is documented and preserved for generations to come and they never go to waste.  Amy Squitieri has followed this rule of thumb throughout her career at Mead and Hunt, having documented dozens of historic bridges, and collaborating with other agencies and groups in preserving dozens more- all of which within her 23+ years at the company and also outside. However her interest in historic bridges came about through working at HABS/HAER and meeting the institute’s legend in the field, Eric DeLony. Her work in the field, carried over into her career at Mead and Hunt (where another historic bridge legend Robert Frame III has also set his mark in the company’s storied history), and thanks to her dedication, many historic bridges have indeed have been given new life in one way or another. This also includes seminars and other works on how to best preserve historic bridges even when funding on the state and federal levels are running thin.  Amy Squitieri was awarded the Lifetime Legacy Award by the Bridgehunter’s Chronicles this past year, and despite running a tight schedule because of bridge-related obligations, I had a chance to do an online interview with her, talking about preservation, ways to overcome obstacles and success stories in her career. Here are some interesting facts about historic bridge preservation from her point of view. Enjoy! 🙂

 

1. What is your favorite bridge in the USA and/or Europe? Why is it your favorite?

 

My current favorite is the Colorado Street Bridge in St. Paul, a large single-span, skewed masonry arch bridge built in 1888 (featured here). The street it carried was abandoned so it now stands forlorn in a public apartment complex. Its unusual arch ring features two different constructions: intrados of brick and extrados with alternating layers of limestone and brick.

 

2. What got you interested in historic bridges? Any personal stories behind it is more than welcome?

 

My first job after graduate school (studied Architectural History at the University of Virginia) was with the Historic American Engineering Record (HAER), working on the Rock Creek Parkway documentation in Washington D.C. Although it was a summer field project, due to the location we were housed in the main National Park Service office. This gave me the chance to work directly with Eric Delony, former chief of HAER and noted pontist. I was assigned as the bridge historian and documented 18 bridges that summer. Within a year, I was a consultant in Wisconsin and coincidentally among my first projects were evaluation and documentation of historic bridges.

 

3. According to the website, you have been working for Mead & Hunt for many years. What does the company do in connection with historic bridges?

 

I’ve been at Mead & Hunt for 23 years and started our cultural resources practice, which includes our specialties in historic roads, bridges and other engineering structures. Mead & Hunt historians and bridge engineers work collaboratively on historic bridge projects nationwide. Our work includes bridge design for rehabilitation projects, statewide historic bridge inventories (conducted in 12 states), Section 106/4f coordination, NEPA documentation, structural analysis and feasibility/alternatives studies.

 

4. Can you share some HB success stories involving Mead & Hunt?

 

We just completed rehabilitation of the Philippi Bridge in West Virginia, led by our Charleston office. The bridge was originally constructed in 1852 and has strong associations with the Civil War. It is the only covered bridge serving the U.S. Highway system and was listed on the National Register of Historic Places in 1972. It was last restored by Emory Kemp in the late 1990s but had extensive deterioration in the roofing and siding. It was dedicated and reopened last month.

 

Mead & Hunt has worked on eligibility evaluations, historical documentation, alternatives studies and/or management plans for more than 200 historic bridges in Minnesota. I played a key role in developing the historian-engineer collaborative team approach to rehabilitating historic bridges implemented in Minnesota since 2007, which has now been applied in the preparation of 150+ individual management plans and ~35 rehabilitation projects. Mead & Hunt brings that same collaborative approach to every historic bridge project regardless of location.

5. Can you describe your role at Mead & Hunt? Slogan and reasons are welcome?

 

I work with a team of other historians and bridge engineers who collectively have many decades of experience with historic bridges of all types. My role on historic bridge projects is Principal Historian. Additionally I have several leadership roles at Mead & Hunt including Vice President, Group Leader and member of the Board of Directors. As a full-service engineering and architectural consulting firm, Mead & Hunt works nationally to deliver projects locally. I lead our Environment and Infrastructure Group to serve client needs in transportation, municipal infrastructure, environmental services, water/wastewater treatment, construction services, energy, and cultural resources. This group is comprised of a diverse team of engineering, environmental, technical, preservation and planning professionals. We function as a trusted partner to our clients, and that partnership results in consistently outstanding solutions.

 

6. The words restore and rehabilitation are sometimes used interchangeably when talking about HBs. Is there a difference between them?

 

Absolutely there’s a difference. Restoration and rehabilitation are two of four separate standards defined within the Secretary of the Interior’s Standards. The other two are preservation and reconstruction. Together the four standards cover the range of actions that may be applied to historic bridges.

 

Rehabilitation is the one we typically follow for historic bridge projects, because it allows for adaptation of a bridge to a new purpose and/or to meet modern design standards. This flexibility is important to developing alternatives and selecting an approach that meets the project’s purpose and need.

 

Restoration is the highest standard and can be difficult to achieve for a bridge that needs to meet a current use; however, it can be applied to restore materials and/or features from the bridge’s significant period. An example is returning lost light standards or restoring a bridge railing that was removed.

 

7. What problems have you identified regarding the following and how have you (and others) found ways to counter them?

 

• Rehabilitating HBs – Historic bridges have a wide range of engineering challenges including structural deterioration, inadequate load capacity, poor geometrics, etc. Project challenges include limited funding, lack of support for preservation, and some owners and engineers being unfamiliar with rehabilitation approaches. We’ve found success by helping owners prioritize and invest in historic bridges that are able to fulfill ongoing transportation needs (this makes it easier to find funding). See below for a new training course that is intended to help educate about successful rehabilitation approaches.

 

• Repurposing HBs – Mead & Hunt helped Minnesota Department of Transportation reinstall the historic Silverdale Bridge as part of the Department of Natural Resources Gateway-Brown’s Creek Trail. The Gateway Trail Iron Bridge is a wrought iron truss bridge constructed in 1873 across Main Street in Sauk Center. In 1937, the bridge was dismantled and moved to Highway 65 in Koochiching County. A new bridge was needed to accommodate heavy logging trucks and modern traffic, so in 2009 the historic bridge was dismantled and stored. Built during the days of the horse and buggy, the bridge again serves horses, along with pedestrian and bicyclists on the Gateway Trail. Challenges included field riveting used for the first time in Minnesota in many decades.

 

• Marketing HBs – We’re not involved in this often but have had previous success helping new owners accept and move several truss bridges in Wisconsin.

 

• Restoring HBs – We’re not involved in restorations per se.

 

8. HBs have dwindled by the hundreds over the past decade. Can you summarize from your perspective why they are being taken down without considering reuse?

 

Limited funding, especially for historic bridges that cannot continue to serve vehicular traffic, is a major challenge. In addition, bridge owners and engineers are often not familiar with available options beyond replacement. To help address this, a team of engineers and historians, including myself, developed a course that is now offered through the National Preservation Institute. The course, Historic Bridges: Management, Regulations, and Rehabilitation, teaches participants how a collaborative approach to rehabilitation projects benefits the regulatory and design process; and how they can identify and apply rehabilitation techniques that will meet engineering and historic preservation standards.

 

9. Engineers, especially agents at the DOT, have used the reason “HBs are functionally obsolete and they are at the end of their useful life. Can you elaborate what they mean and do you agree/disagree with the statement?

 

I don’t hear functional obsolescence used as a particular reason to replace bridges. I see the engineers I work with at Mead & Hunt and various state DOTs take a more holistic approach to evaluating alternatives for historic bridges. Foremost, we consider project purpose and need, which is a key part of the U.S. regulatory process. In addition, these factors are important to future use: rehabilitation potential, load capacity, geometrics on bridge and approach roadway, available detour for heavier trucks, and, where applicable, other restrictive factors (e.g. boat or rail traffic beneath). Our work focuses on keeping bridges in transportation use—typically for vehicles but sometimes for pedestrians, bikes and/or horses.

 

10. Wisconsin, where Mead & Hunt is located is on a modernization spree at the cost of many HBs. Any reasons behind that?

 

Mead & Hunt has offices across the nation, and I wouldn’t say we are on a “modernization spree” in any of the states where we operate. This is because currently money for infrastructure and transportation projects is pretty tight and many states are focused on asset management and maintenance and preservation projects. However, I’d agree that there generally isn’t much support for historic bridge preservation in Wisconsin. A notable exception would be the City of Milwaukee which we’ve helped to rehabilitate several bascule bridges, including on Cherry and State Streets and Kilbourn Avenue.

 

11. What projects are you and your crew undertaking at the moment?

 

We’re in year five of putting in place the Louisiana Department of Transportation and Development’s historic bridge program. An early step involved review of more than 4,500 state and locally owned bridges constructed through 1970. This groundbreaking effort proactively identified 150 historic structures, allowing the LADOTD to consider these historic resources early in project planning and development. The state has committed to preserve 33 historic bridges that we identified as the best candidates for preservation.  The capstone of the program is a Programmatic Agreement that outlines procedures for managing the state’s historic bridges, streamlines coordination under Section 106 of the National Historic Preservation Act, and provides public outreach, training, and funding for historic bridges.  An award-winning publication, historic documentation, and marketing bridges for reuse provides mitigation for historic bridges that were found inadequate to serve in long-term transportation use. We’re in the final stages of preparing individual management plans to guide the preservation of the 33 priority bridges.

 

We are just starting a multi-phase project in Georgia to identify historic bridges and develop management recommendations.

 

12. What would you personally like to see done re. the remaining HBs in the U.S.?

 

I’m generally an optimist and see several positive trends for historic bridges. The current focus on maintaining aging infrastructure as states work with limited funding has owners working to extend the useful life of bridges, including those that have historic significance. Through training opportunities and better collaboration, professionals and owners are seeing more options to keep historic bridges in use.

 

I’m also a realist and recognize that you can’t save every historic bridge. I’d like to see more proactive efforts to conduct maintenance and rehabilitation activities before deterioration advances too far. More money for repairing old bridges in general—and including those that are historic—would be great. Infrastructure overall is woefully underfunded. Special funding is needed for truss and covered bridges to be repurposed on trails when they can no longer serve vehicles, since most government funding is restricted to bridges that carry vehicular traffic.

13. Any bridges you would like to see before you retire?

 

Retirement is quite a few years off for me but I enjoy traveling in the U.S. and abroad. I would particularly like to see the Forth Bridge in Scotland and the work of Robert Maillart in Switzerland. Once I retire, I plan to travel even more.

Odds and Ends: Eleven as the Magical Number

As we close in on the end of the year, we find that the number eleven is the magical number. Eleven is a tribute to the people who have made a difference, big or small, but whose lives were cut short because of tragedy. Eleven is the number which has been popping up recently because of three events that have hit home:

1. It marks an end of 27 years of sorrow and worries as an 11-year old boy has come home to rest. Jacob Wetterling was kidnapped on 22 October, 1989 while returning home on a rural road near St. Joesph, Minnesota. His remains were found on 1 September, 2016, by a man who later admitted that he had kidnapped and murdered him. While he is currently behind bars awaiting sentencing, millions of people have cried, stopped by the site of the murder to lay flowers and have even done tributes for the boy, whose dreams of being an athlete were shattered one cold fall night. Jacob’s mother Patty addressed a crowd of people asking what can be done for the family (which you can read here) Even a poem in his memory can be found on sister column The Flensburg Files for you to read here.
2. It marks the 15th anniversary of another tragedy but with larger proportions as two planes, on the morning of 11 September, 2001, crashed into the World Trade Center in New York, another into the Pentagon in Washington and another in Pennsylvania despite being enroute to the White House. This event has changed the world in many aspects, yet we still don’t understand how this could happen.
3. It symbolizes the ongoing Spring Revolution in the Middle East and northern Africa, which happened five years ago in seven countries, including the conflicting country of Syria.

In honor of those, whose lives were unnecessarily cut short and whose dreams of becoming a professional in their field of interest were shattered, the Bridgehunter’s Chronicles will be wearing a special avatar between now and the end of the 2016 Othmar Ammann Awards on its areavoices website and in some posts in the wordpress website. This is an important way of showing solidarity with the families and friends of those whose lives ended too early. You will find the logo here, and it will be used in all articles to come:

It’s an arch bridge at sunrise, crossing a large body of water, showing solidarity between parties, and bring peace and prosperity to all. Jacob’s name symbolizes every child’s dream and hope for a better life, which can only happen if we as parents, teachers, historians and the like can help them make it happen.

Othmar H. Ammann Awards underway earlier than expected.

Furthermore, entries are being taken earlier than expected for this year’s Othmar H. Ammann Awards, the awards where we take pride in the areas historic and unique bridges in the USA, Europe and elsewhere. The reason behind this is twofold:

1. This year is the fifth anniversary of the Ammann Awards. To commemorate the event, the Chronicles’ Hall of Fame will be established, which will feature the top six finishers of each category, plus the inductees from the Lifetime Legacy. Therefore, there will be two rounds of voting for this year’s awards: The first round will be for the 2016 Awards, while the second round will feature the voting of all the winners and runners-up in each of the categories dating back to 2011, with the top six overall being inducted. The Hall of Fame page will appear in the Chronicles’ wordpress page.
2. In light of the recent tragedy in Minnesota, but also in connection with the 50th anniversary of the National Register of Historic Places and the 100th anniversary of the National Park Service, starting the contest early will help families take their children on photo tours of several historic bridges in the US to show them the importance of bridges in the development of the US infrastructure. As Europe has some gorgeous historic bridges that are two centuries old in many places, people there can share their experiences in preserving them with their American counterparts. So taking a parent’s advice, take your kids out and show them how bridges shaped your countries, spend some time with them taking pictures and writing essays about your favorite bridge(s), and send them to Jason Smith at the Chronicles at: flensburg.bridgehunter.av@googlemail.com. Entries in other languages are welcomed.

More information on how to enter the 2016 Ammann Awards in the categories of best photo, bridge of the year, lifetime achievement, tour guide of the bridges in the region, and best kept secret can be found here. Deadline for all entries is 1 December 2016 with voting to follow. The winners will be announced on 11 January, 2017 for both the annual awards as well as the Hall of Fame.

Please note, the contest is open for everyone both in the US as well as Europe and elsewhere.

A series on the National Register of Historic Places and the role of historic bridges is in the works which includes interviews and other comments. They will be posted in both wordpress and areavoices versions. In addition, the author has several bridge tours in eastern Germany, which will be added in the coming weeks. Stay tuned for more from the Chronicles.
