a meeting held near the end of 1881. The project would include building a terminal in downtown Minneapolis and connecting the rails to the Manitoba Railway, the execution for which was accomplished by the Minneapolis Union Railway company, a team that was built for the sole purpose of overseeing the project. The stockholders met for the first time immediately the following year and Col. Charles C. Smith was selected as the head engineer. The bridge has been altered somewhat from its original appearance. When the Upper Lock and Dam were built at Saint Anthony Falls, two of the arches were replaced with a moveable truss so barges could pass through the lock. Later, in 1965, flood waters undermined three of the piers and caused the bridge to sag fourteen inches. The bridge was repaired by strengthening the piers and reinforcing underneath two of the arches. When it was in rail service, the bridge carried trains of many railroads to and from the Minneapolis Great Northern Depot, including the Great Northern Railway's Empire Builder. The bridge ceased to be used as a railroad bridge in 1978, and after a period of disuse, was repaired and adapted in the early 1990s to its present use. The bike and walking trails across the bridge are integrated into the city's park and trail system, and form part of the St Anthony Falls Heritage Trail, which includes interpretive plaques describing the history of the area. The most recent renovations—including indirect lighting—were completed in late 2005. The lighting was paid for by private donations. During the summer months, the Stone Arch Bridge is a focus of numerous festivals in the area of St. Anthony Main and Historic Main Street. The Stone Arch Festival of the Arts occurs Father's Day weekend and features many local artists. Fireworks displays on the Fourth of July and during the Minneapolis Aquatennial in late July also bring crowds; fireworks are launched from nearby Hennepin Island. The bridge offers views of the Minneapolis skyline, Pillsbury "A" Mill, the Mill City Museum, and many other places in the district, and is near both the restaurants of Main St SE and the Guthrie Theater.
