Best known for its 19th and 20th century architecture, the City of Marshall has been referred to by the National Register of Historic Places as a "virtual textbook of 19th-Century American architecture." Its historic center, the Marshall Historic District, is one of the nation's largest architecturally significant National Historic Landmark Districts. 

When a deteriorating bridge on Monroe Street over Rice Creek needed to be replaced, the city wanted the new structure to mimic the look of its current infrastructure and its historic landmarks. Built in 1891, the original masonry arch bridge was constructed by local artisans, Gustavus A. Mumaw and Henry Briegel, of the firm Mumaw & Briegel. The bridge received repairs in the mid-1990s, including shotcrete along the west fascia and modern railings. 

In addition to an aesthetic appearance, it was imperative that the new structure be able to accommodate the tight constraints of the site, as well as the utilities in the area. The site access and construction area were extremely limited with a house located 40 feet from the southeast corner of the structure and an existing pedestrian bridge located 20 feet west of the structure. Overhead utilities on both sides of the road limited equipment movement and general construction. Last but not least, the arch system needed to accommodate a 20" opening for an existing sanitary sewer that could not be relocated.

As the best solution to meet all of these requirements, the city selected a 47' x 12'-3" CON/SPAN® O-Series® Bridge System, 36' in length, as the best replacement option. In order to maintain the limited right-of-way, the structure was designed with a 3 degree skew. The design also included precast headwalls and wingwalls with the headwalls transitioning into a cast-in-place barrier wall. In order to accommodate the aesthetics requirement, the city selected a decorative fascia that meshed well with the historic structures and buildings in the area.

“Finding the correct replacement structure was a unique and challenging part of this project since it had to meet the design requirements of the state, while also meeting the aesthetic desires of the city," concluded Amanda Hemeyer, Project Manager at Rowe Professional Services Company. "While the original structure was not listed on the National Historic Registry, the city wanted to maintain the look of the original bridge. The shape of the CON/SPAN structure was ideal for this application as it provided a natural arch, while the precast wall system included a stone formliner to mimic the look of the original masonry.“
